Name of the Vulnerable Software and Affected Versions GPAC version 1.0.1

Description The issue is caused by an integer overflow in the gf avc read pps bs internal function in media tools/av parsers.c. This occurs because pps id can be a negative number, leading to an overflow since avc->pps only has 255 units, resulting in a crash.

Recommendations For GPAC version 1.0.1, as a temporary workaround, consider disabling the gf avc read pps bs internal function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
