Уязвимость мультимедийной библиотеки FFmpeg, связанная с недостатками разграничения доступа, позволяющая нарушителю повысить свои привелегии

A null pointer dereference issue was discovered in 'FFmpeg' in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash.

libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).

No data currently available.

A vulnerability was found in FFmpeg up to 7.0.1. It has been classified as critical. This affects the function pnm_decode_frame in the library /libavcodec/pnmdec.c. The manipulation leads to heap-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 7.0.2 is able to address this issue. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-273651.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In version 2.10 and earlier, PJSIP transport can be reused if they have the same IP address + port + protocol. However, this is insufficient for secure transport since it lacks remote hostname authentication. Suppose we have created a TLS connection to `sip.foo.com`, which has an IP address `100.1.1.1`. If we want to create a TLS connection to another hostname, say `sip.bar.com`, which has the same IP address, then it will reuse that existing connection, even though `100.1.1.1` does not have certificate to authenticate as `sip.bar.com`. The vulnerability allows for an insecure interaction without user awareness. It affects users who need access to connections to different destinations that translate to the same address, and allows man-in-the-middle attack if attacker can route a connection to another destination such as in the case of DNS spoofing.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In PJSIP version 2.10 and earlier, after an initial INVITE has been sent, when two 183 responses are received, with the first one causing negotiation failure, a crash will occur. This results in a denial of service.

Уязвимость централизованной системы управления версиями Subversion, связанная с неправильной авторизацией, позволяющая нарушителю получить доступ к конфиденциальным данным

Уязвимость модуля mod_dav_svn централизованной системы управления версиями Subversion, позволяющая нарушителю вызвать отказ в обслуживании

Apache Subversion SVN authz protected copyfrom paths regression Subversion servers reveal 'copyfrom' paths that should be hidden according to configured path-based authorization (authz) rules. When a node has been copied from a protected location, users with access to the copy can see the 'copyfrom' path of the original. This also reveals the fact that the node was copied. Only the 'copyfrom' path is revealed; not its contents. Both httpd and svnserve servers are vulnerable.

Subversion's mod_dav_svn is vulnerable to memory corruption. While looking up path-based authorization rules, mod_dav_svn servers may attempt to use memory which has already been freed. Affected Subversion mod_dav_svn servers 1.10.0 through 1.14.1 (inclusive). Servers that do not use mod_dav_svn are not affected.

Уязвимость функции do_activate() пакета mgetty, позволяющая нарушителю выполнить произвольные команды

An issue was discovered in mgetty before 1.2.1. In fax/faxq-helper.c, the function do_activate() does not properly sanitize shell metacharacters to prevent command injection. It is possible to use the ||, &&, or > characters within a file created by the "faxq-helper activate " command.

An issue was discovered in mgetty before 1.2.1. In contrib/scrts.c, a stack-based buffer overflow can be triggered via a command-line parameter.

An issue was discovered in mgetty before 1.2.1. In contrib/next-login/login.c, the command-line parameter username is passed unsanitized to strcpy(), which can cause a stack-based buffer overflow.

An issue was discovered in mgetty before 1.2.1. In fax_notify_mail() in faxrec.c, the mail_to parameter is not sanitized. It could allow for command injection if untrusted input can reach it, because popen is used.

An issue was discovered in mgetty before 1.2.1. In fax_notify_mail() in faxrec.c, the mail_to parameter is not sanitized. It could allow a buffer overflow if long untrusted input can reach it.

mgetty prior to version 1.2.1 is affected by: Infinite Loop. The impact is: DoS, the program does never terminates. The component is: g3/g32pbm.c. The attack vector is: Local, the user should open a specially crafted file. The fixed version is: 1.2.1.

mgetty prior to 1.2.1 is affected by: out-of-bounds read. The impact is: DoS, the program may crash if the memory is not mapped. The component is: putwhitespan() in g3/pbm2g3.c. The attack vector is: Local, the victim must open a specially crafted file. The fixed version is: 1.2.1.
