Name of the Vulnerable Software and Affected Versions GPAC versions prior to v1.0.1

Description The issue is related to an infinite loop vulnerability in the ISOBMFF reader filter, specifically in the isoffin read.c file. The isoffin process() function can result in a Denial of Service (DoS) due to an infinite loop. To exploit this, the victim must open a specially crafted mp4 file.

Recommendations For GPAC versions prior to v1.0.1, update to version v1.0.1 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the isoffin process() function until a patch is available. Restrict access to specially crafted mp4 files to minimize the risk of exploitation.
