How to fix?

Upgrade Debian:11 gpac to version 1.0.1+dfsg1-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gpac package and not the gpac package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

AVC_DuplicateConfig() at isomedia/avc_ext.c in GPAC 0.7.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file. There is "cfg_new->AVCLevelIndication = cfg->AVCLevelIndication;" but cfg could be NULL.
