CVE-2020-22037

Name of the Vulnerable Software and Affected Versions FFmpeg version 4.2

Description The issue is related to a memory leak in the avcodec alloc context3 function at options.c in the FFmpeg library. This leak occurs due to incorrect memory deallocation before the last reference is removed. Exploitation of this issue allows a remote attacker to cause a denial of service.

Recommendations For FFmpeg version 4.2, consider disabling the avcodec alloc context3 function as a temporary workaround until a patch is available. Restrict access to the options.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 vulnerability.
