Name of the Vulnerable Software and Affected Versions: Libav version 12.2

Description: The issue allows remote attackers to cause a denial of service, specifically a heap-based buffer over-read, by providing a crafted audio file. This is related to the mpc8 probe function in libavformat/mpc8.c.

Recommendations: For Libav version 12.2, consider avoiding the use of the mpc8 probe function until a patch is available. As a temporary workaround, restrict the processing of crafted audio files to minimize the risk of exploitation.
