Name of the Vulnerable Software and Affected Versions FFmpeg version 4.2

Description A Denial of Service issue exists due to a memory leak in the av dict set function in dict.c. This is caused by incorrect memory deallocation before removing the last reference, allowing a remote attacker to cause a denial of service.

Recommendations For FFmpeg version 4.2, as a temporary workaround, consider disabling the av dict set function until a patch is available. Restrict access to the dict.c component to minimize the risk of exploitation.
