libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future trailers since the stored size was one byte less than required. The problem is that the code that creates HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer, while this was recently changed to `: ` (a space was added after the colon) but the following math wasn't updated correspondingly. When accessed, the data is read out of bounds and causes either a crash or that the (too large) data gets passed to client write. This could lead to a denial-of-service situation or an information disclosure if someone has a service that echoes back or uses the trailers for something.

The inode_init_owner function in fs/inode.c in the Linux kernel through 4.17.4 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.

Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.

curl supports "globbing" of URLs, in which a user can pass a numerical rangeto have the tool iterate over those numbers to do a sequence of transfers.In the globbing function that parses the numerical range, there was anomission that made curl read a byte beyond the end of the URL if given acarefully crafted, or just wrongly written, URL. The URL is stored in a heapbased buffer, so it could then be made to wrongly read something else insteadof crashing.

Enea fix: Enea Linux 7.0

When doing an TFTP upload and curl/libcurl is given a URL that contains a verylong file name (longer than about 515 bytes), the file name is truncated tofit within the buffer boundaries, but the buffer size is still wrongly updatedto use the untruncated length. This too large value is then used in the`send()` call, making curl attempt to send more data than what is actually putinto the buffer. The `send()` function will then read beyond the end of theheap based buffer.

Enea fix: Enea Linux 7.0

 libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.

Enea fix: Enea Linux 7.0

A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.

libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate (or no certificate).

There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). Note: The impact from this issue is similar to CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL version 1.0.2-1.0.2m and 1.1.0-1.1.0g are affected. Fixed in OpenSSL 1.0.2n. Due to the low severity of this issue we are not issuing a new release of OpenSSL 1.1.0 at this time. The fix will be included in OpenSSL 1.1.0h when it becomes available. The fix is also available in commit e502cc86d in the OpenSSL git repository.

 Enea fix: Enea Linux 7.0 (upstream)

OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL 1.0.2n. OpenSSL 1.1.0 is not affected.

Enea fix: Enea Linux 7.0 (upstream)

There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen.

curl and libcurl support "OCSP stapling", also known as the TLS Certificate Status Request extension (using the CURLOPT_SSL_VERIFYSTATUS option). When telling curl to use this feature, it uses that TLS extension to ask for a fresh proof of the server's certificate's validity. If the server doesn't support the extension, or fails to provide said proof, curl is expected to return an error.

Due to a coding mistake, the code that checks for a test success or failure, ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. Contrary to how it used to function and contrary to how this feature is documented to work.

This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.

This flaw also exists in the command line tool (--cert-status).

Affected Enea Linux Release/s:

 Enea fix: Enea Linux 7.0 (from upstream)

A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of service.

 Enea fix: Enea Linux 7.0

Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while destroying gpu resource object in 'virtio_gpu_resource_destroy'. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.

Enea fix: Enea Linux 6.0

Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to an information leakage issue. It could occur while processing 'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could use this flaw to leak contents of the host memory bytes.

Enea fix: Enea Linux 6.0

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option.

Enea fix: QorIQ 4.1

 libcurl's (new) internal function that returns a good 32bit random value was implemented poorly and overwrote the pointer instead of writing the value into the buffer the pointer pointed to. This random value is used to generate nonces for Digest and NTLM authentication, for generating boundary strings in HTTP formposts and more. Having a weak or virtually non-existent random there makes these operations vulnerable. This function is brand new in 7.52.0.

Enea fix: Enea Linux 6.0

libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. The bug occurs when the conversion outputs more than 255 bytes. The flaw happens because the floating point conversion is using system functions without the correct boundary checks.

Enea fix: Enea Linux 6.0

Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions.

Enea fix: QorIQ 4.1

When curl is built with libidn to handle International Domain Names (IDNA), it translates them to puny code for DNS resolving using the IDNA 2003 standard, while IDNA 2008 is the modern and up-to-date IDNA standard.

This misalignment causes problems with for example domains using the German ß character (known as the Unicode Character 'LATIN SMALL LETTER SHARP S') which is used at times in the .de TLD and is translated differently in the two IDNA standards, leading to users potentially and unknowingly issuing network transfer requests to the wrong host.

Enea fix: Enea Linux 6.0

curl doesn't parse the authority component of the URL correctly when the host name part ends with a '#' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.

Enea fix: Enea Linux 6.0

libcurl explicitly allows users to share cookies between multiple easy handles that are concurrently employed by different threads. When cookies to be sent to a server are collected, the matching function collects all cookies to send and the cookie lock is released immediately afterwards. That funcion however only returns a list with *references* back to the original strings for name, value, path and so on. Therefore, if another thread quickly takes the lock and frees one of the original cookie structs together with its strings, a use-after-free can occur and lead to information disclosure. Another thread can also replace the contents of the cookies from separate HTTP responses or API calls.

Enea fix: Enea Linux 6.0

The URL percent-encoding decode function in libcurl is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer. This can be triggered by a user on a 64bit system if the user can send in a custom (very large) URL to a libcurl using program.

Enea fix: Enea Linux 6.0

The `curl_getdate` converts a given date string into a numerical timestamp and it supports a range of different formats and possibilites to express a date and time. The underlying date parsing function is also used internally when parsing for example HTTP cookies (possibly received from remote servers) and it can be used when doing conditional HTTP requests. The date parser function uses the libc sscanf() function at two places, with the parsing strings "%02d:%02d" and ""%02d:%02d:%02d". The intent being that it would parse either a string with HH:MM (two digits colon two digits) or HH:MM:SS (two digits colon two digits colon two digits). If instead the piece of time that was sent in had the final digit cut off, thus ending with a single-digit, the date parser code would advance its read pointer one byte too much and end up reading out of bounds.

Enea fix: Enea Linux 6.0

The curl tool's "globbing" feature allows a user to specify a numerical range through which curl will iterate. It is typically specified as [1-5],
specifying the first and the last numbers in the range. Or with [a-z], using letters.

1. The curl code for parsing the second *unsigned* number did not check for aleading minus character, which allowed a user to specify `[1--1]` with no complaints and have the latter `-1` number get turned into the largest unsigned long value the system can handle. This would ultimately cause curl to write outside the dedicated malloced buffer after no less than 100,000 iterations, since it would have room for 5 digits but not 6.

2. When the range is specified with letters, and the ending letter is left out `[L-]`, the code would still advance its read pointer 5 bytes even if the string was just 4 bytes and end up reading outside the given buffer 

 In curl's implementation of the Kerberos authentication mechanism, the function `read_data()` in security.c is used to fill the necessary krb5 structures. When reading one of the length fields from the socket, it fails to ensure that the length parameter passed to realloc() is not set to 0. This would lead to realloc() getting called with a zero size and when doing so realloc() returns NULL *and* frees the memory - in contrary to normal realloc() fails where it only returns NULL - causing libcurl to free the memory *again* in the error path. This flaw could be triggered by a malicious or just otherwise ill-behaving server.

The libcurl API function called `curl_maprintf()` can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables. The function is also used internallty in numerous situations. The function doubles an allocated memory area with realloc() and allows the size to wrap and become zero and when doing so realloc() returns NULL *and* frees the memory - in contrary to normal realloc() fails where it only returns NULL - causing libcurl to free the memory *again* in the error path. Systems with 64 bit versions of the `size_t` type are not affected by this issue. This behavior is triggable using the publicly exposed function.

 In libcurl's base64 encode function, the output buffer is allocated as follows without any checks on insize: malloc( insize * 4 / 3 + 4 ) On systems with 32-bit addresses in userspace (e.g. x86, ARM, x32), the multiplication in the expression wraps around if insize is at least 1GB of data. If this happens, an undersized output buffer will be allocated, but the full result will be written, thus causing the memory behind the output buffer to be overwritten. If a username is set directly via `CURLOPT_USERNAME` (or curl's `-u, --user` option), this vulnerability can be triggered. The name has to be at least 512MB big in a 32bit system. Systems with 64 bit versions of the `size_t` type are not affected by this issue.

When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.

If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar. The issue pertains to the function that loads cookies into memory, which reads the specified file into a fixed-size buffer in a line-by-line manner using the `fgets()` function. If an invocation of fgets() cannot read the whole line into the destination buffer due to it being too small, it truncates the output. This way, a very long cookie (name + value) sent by a malicious server would be stored in the file and subsequently that cookie could be read partially and crafted correctly, it could be treated as a different cookie for another server. 

An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31349935.

Enea fix: QorIQ 4.1

It was found that provided string length arguments in four libcurl functions curl_escape(), curl_easy_escape(), curl_unescape and curl_easy_unescape were not properly checked and due to arithmetic in the functions, passing in the length 0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up causing an allocation of zero bytes of heap memory that curl would attempt to write gigabytes of data into. This flaw does not affect the curl command line tool. 

 After testing original CVE-2016-5420 patch, it was discovered that libcurl built on top of NSS (Network Security Services) still incorrectly re-uses client certificates if a certificate from file is used for one TLS connection but no certificate is set for a subsequent TLS connection.

The IP stack in the Linux kernel through 4.8.2 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666.

Enea fix: QorIQ 4.1

The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset.

Enea fix: Enea Linux 7.0 (from upstream)

libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, or when explicitly asked to use SSLv3. This flaw only exists when libcurl is built to use mbedTLS or PolarSSL as TLS backend. The documentation for mbedTLS and PolarSSL (wrongly) says that the API function *ssl_set_hostname() is used only for setting the name for the TLS extension SNI. The set string is however even more importantly used by the libraries to verify the server certificate, and if no "hostname" is set it will just skip the check and successfully continue with the handshake. libcurl would wrongly avoid using the function when the specified host name was given as an IP address or when SSLv3 is used, as SNI isn't supposed to be used then. This then leads to that all uses of TLS oriented protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc) will allow connections to servers with unverified server certificates as long as they're specified as IP addresses or using SSLv3. By tricking a libcurl-using client to use a URL with a host specified as IP address only, an application could be made to connect to an impostor server or Man In The Middle host without noticing.

Enea fix: Enea Linux 6.0

The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.

Enea fix: Enea Linux 5.0

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a "DROWN" attack.

libssh versions 0.1 and above have a bits/bytes confusion bug and generate the an anormaly short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively. There are practical algorithms (Baby steps/Giant steps, Pollard's rho) that can solve this problem in O(2^63) operations. Both client and server are are vulnerable, pre-authentication. This vulnerability could be exploited by an eavesdropper with enough resources to decrypt or intercept SSH sessions.
The bug was found during an internal code review by Aris Adamantiadis of the libssh team.
