Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions FFmpeg versions prior to 4.2

Description The issue is related to a NULL pointer dereference in the avcodec open2 function in libavcodec/utils.c. This could potentially allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.

Recommendations For FFmpeg versions prior to 4.2, update to version 4.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the avcodec open2 function in libavcodec/utils.c to minimize the risk of exploitation.
