CVE-2021-21853

Name of the Vulnerable Software and Affected Versions GPAC Project on Advanced Content library version 1.0.1

Description The issue is related to the MPEG-4 decoding functionality of the GPAC multimedia platform, where an integer overflow vulnerability exists due to unchecked addition arithmetic. This can cause a heap-based buffer overflow, leading to memory corruption. An attacker can exploit this by convincing a user to open a specially crafted MPEG-4 video, potentially allowing them to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For GPAC Project on Advanced Content library version 1.0.1, consider updating to a newer version that addresses the integer overflow vulnerability in the MPEG-4 decoding functionality. As a temporary workaround, restrict the use of the MPEG-4 decoding function to minimize the risk of exploitation. Avoid opening videos from untrusted sources until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
