Name of the Vulnerable Software and Affected Versions FFmpeg version 4.2

Description A heap-based Buffer Overflow issue exists in the crossfade samples fltp function of the libavfilter/af afade.c component, potentially leading to memory corruption. This could allow a remote attacker to impact the integrity, availability, and confidentiality of information.

Recommendations For FFmpeg version 4.2, consider disabling the crossfade samples fltp function as a temporary workaround until a patch is available. Restrict access to the libavfilter/af afade.c component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
