Name of the Vulnerable Software and Affected Versions FFmpeg version 4.2

Description The issue is related to a heap-based Buffer Overflow Vulnerability in the convolution y 8bit function of the FFmpeg library. This vulnerability could allow a remote attacker to cause a Denial of Service. The vulnerability is associated with a buffer overflow, which can be triggered by a malicious user.
