NixOS vulnerability analysis and mitigation
Overview
The AV1_DuplicateConfig function in GPAC 1.0.1 allows attackers to cause a denial of service via a NULL pointer dereference vulnerability (NVD).
Technical details
The vulnerability exists in the AV1_DuplicateConfig function within GPAC 1.0.1's codebase. The issue occurs when the function attempts to duplicate an AV1 configuration without properly validating that the input configuration pointer and its members are non-null (GitHub Commit).
Impact
When successfully exploited, this vulnerability can lead to a denial of service condition through application crashes caused by null pointer dereference (NVD).
Exploitability
The vulnerability can be triggered by providing specially crafted input that leads to a null configuration being processed by the AV1_DuplicateConfig function (GitHub Issue).
Mitigation and workarounds
The issue has been fixed in later versions of GPAC through additional null pointer checks in the AV1_DuplicateConfig function and related code paths (GitHub Commit).
