GStreamer AV1 Codec 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 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 heap-based buffer. An attacker can leverage
this vulnerability to execute code in the context of the current process.
Was ZDI-CAN-22226.
