CVE-2023-44446

GStreamer MXF File Parsing Use-After-Free 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 MXF video files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22299.

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.
