Name of the Vulnerable Software and Affected Versions

Description
The issue is related to a Buffer Overflow in the
filter edges function located in libavfilter/vf yadif.c, which could allow a remote malicious user to cause a Denial of Service. This can be exploited by a remote attacker, potentially leading to service disruption.Recommendations
For FFmpeg version 4.2, consider disabling the
filter edges function in libavfilter/vf yadif.c as a temporary workaround to minimize the risk of exploitation. Restrict access to the vf yadif.c module to reduce the likelihood of a Denial of Service attack. Avoid using the affected function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
