NixOS vulnerability analysis and mitigation
Overview
GPAC mp4box version 1.1.0-DEV-rev1727-g8be34973d-master contains a use-after-free vulnerability in the function gfnodegetattributeby_tag. The vulnerability was discovered in February 2022 and affects the XML namespace handling functionality in the GPAC multimedia framework (Debian Security, GitHub Issue).
Technical details
The vulnerability occurs in the gfnodegetattributebytag function within the src/scenegraph/xmlns.c file. When processing XML namespace attributes, the code attempts to access memory that has been previously freed, leading to a use-after-free condition. This was detected by AddressSanitizer during testing with specific LSR (LASeR) content (GitHub Issue).
Impact
The use-after-free vulnerability could potentially lead to program crashes (denial of service) or possibly arbitrary code execution in the context of the application (Debian Security).
Mitigation and workarounds
For Debian bullseye users, the vulnerability has been fixed in version 1.0.1+dfsg1-4+deb11u2. Users are recommended to upgrade their gpac packages to the patched version (Debian Security).
