Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions GPAC versions 1.0.1

Description The issue is related to the co64 decoder functionality in the GPAC multimedia platform, specifically in the MPEG-4 decoding. It involves incorrect checking of the result of an arithmetic operation, which can lead to memory corruption. An attacker can exploit this by providing a specially crafted MPEG-4 input, potentially allowing them to access confidential data, compromise data integrity, and cause a denial of service. The vulnerability can be triggered when a user opens a maliciously crafted video.

Recommendations For GPAC version 1.0.1, consider disabling the co64 decoder functionality until a patch is available to prevent potential exploitation. Restrict access to the MPEG-4 decoding functionality to minimize the risk of memory corruption and data compromise. Avoid using the GPAC library to decode MPEG-4 inputs from untrusted sources until the issue is resolved.
