Base vector

AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions libaom versions prior to 2021-04-07

Description The issue is related to the incorrect handling of memory in the aom image.c component of the libaom library, which implements the AV1 codec. This can potentially allow a remote attacker to execute arbitrary code. The problem is caused by the freeing of memory that is not located on the heap.

Recommendations For versions prior to 2021-04-07, update to a version released after 2021-04-07 to resolve the issue. As a temporary workaround, consider restricting access to the aom image.c component until a patch is available.
