Name of the Vulnerable Software and Affected Versions
FFmpeg version 4.2
Description
A heap-based Buffer Overflow issue exists in the gaussian blur component of the FFmpeg library, specifically at libavfilter/vf edgedetect.c. This could lead to memory corruption and other potential consequences. Exploitation of this issue may allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
Recommendations
For FFmpeg version 4.2, consider disabling the gaussian blur function in the libavfilter/vf edgedetect.c module as a temporary workaround until a patch is available. Restrict access to the vulnerable 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.
