Summary
OpenH264 recently reported a [heap overflow](https://github.com/cisco/openh264/security/advisories/GHSA-m99q-5j7x-7m9x) that was fixed in upstream [63db555](https://github.com/cisco/openh264/commit/63db555e30986e3a5f07871368dc90ae78c27449) and [integrated into](https://github.com/ralfbiedert/openh264-rs/commit/3a822fff0b4c9a984622ca2b179fe8898ac54b14) 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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
