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.
