Summary
OpenH264 Rust API Openh264 Decoding Functions Heap Overflow Vulnerability
Details

OpenH264 recently reported a heap overflow that was fixed in upstream 63db555 and integrated into our 0.6.6 release. For users relying on Cisco's pre-compiled DLL, we also published 0.8.0, which is compatible with their latest fixed DLL version 2.6.0.

In other words: - if you rely on our source feature only, >=0.6.6 should be safe, - if you rely on libloading, you must upgrade to 0.8.0 and use their latest DLL >=2.6.0.

Users handling untrusted video files should update immediately.

Severity
8.6 (High)
