Affected: AlmaLinux:9: gstreamer1-plugins-bad-free, AlmaLinux:9: gstreamer1-plugins-bad-free-devel

GStreamer is a streaming media framework based on graphs of filters which operate on media data. The gstreamer1-plugins-bad-free package contains a collection of plug-ins for GStreamer.

Security Fix(es):

* gstreamer-plugins-bad: Integer overflow leading to heap overwrite in MXF file handling with uncompressed video (CVE-2023-40474) * gstreamer-plugins-bad: Integer overflow leading to heap overwrite in MXF file handling with AES3 audio (CVE-2023-40475) * gstreamer-plugins-bad: Integer overflow in H.265 video parser leading to stack overwrite (CVE-2023-40476) * gstreamer-plugins-bad-free: buffer overflow vulnerability (CVE-2023-50186)

GStreamer AV1 Video Parsing Stack-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 metadata within AV1 encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22300.
