CVE-2021-21856

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

Description The issue is related to integer overflow vulnerabilities in the MPEG-4 decoding functionality. A specially crafted MPEG-4 input can cause an integer overflow due to unchecked addition arithmetic, resulting in a heap-based buffer overflow that causes memory corruption. An attacker can trigger this issue by convincing a user to open a video. The vulnerability allows a remote attacker 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 disabling the MPEG-4 decoding functionality until a patch is available to prevent exploitation. Restrict access to videos that could potentially trigger the vulnerability to minimize the risk of memory corruption and data compromise. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
