CVE-2023-37329

GStreamer SRT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.

The specific flaw exists within the parsing of SRT subtitle files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20968.

GStreamer is a pipeline-based multi media framework that links together a wide variety of media processing systems to complete complex workflows, based on graphs of filters which operate on media data. This package contains plug-ins that are not tested well enough yet, or the code is not of good enough quality.

Security Fix(es):

Heap-based buffer overflow in the PGS blu-ray subtitle decoder when handling certain files in GStreamer versions before 1.22.4 / 1.20.7. It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through heap manipulation.

A use-after-free flaw was found in the MXF demuxer in GStreamer when handling certain MXF video files. This issue could allow a malicious third party to trigger a crash in the application and may allow code execution.(CVE-2023-44446)

It was discovered that GStreamer Bad Plugins incorrectly handled certain media files. A remote attacker could use this issue to cause GStreamer Bad Plugins to crash, resulting in a denial of service, or possibly execute arbitrary code.

It was discovered that multiple plugins in GStreamer contained arithmetic overflows. An attacker could possibly use this issue to cause applications using the plugins to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-37329, CVE-2023-40474, CVE-2023-40475, CVE-2023-40476)
