Name of the Vulnerable Software and Affected Versions Gpac versions through 1.0.1

Description A buffer overflow issue exists via a malformed MP4 file in the svc parse slice function in av parsers.c, allowing attackers to cause a denial of service, potentially execute code, and escalate privileges.

Recommendations For Gpac versions through 1.0.1, as a temporary workaround, consider restricting the use of the svc parse slice function until a patch is available. Avoid processing malformed MP4 files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
