Name of the Vulnerable Software and Affected Versions FFmpeg version 4.2

Description A heap-based Buffer Overflow issue exists in the filter frame function at libavfilter/vf bitplanenoise.c, potentially leading to memory corruption and other consequences. This issue may allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.
