      <title>RUSTSEC-2025-0008 — Openh264 Decoding Functions Heap Overflow Vulnerability</title>
      <link>https://vulnerability.circl.lu/vuln/rustsec-2025-0008</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; crates.io: openh264-sys2&lt;/p&gt;
&lt;p&gt;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&amp;#39;s pre-compiled DLL, we also published 0.8.0, which is compatible with their latest fixed DLL version  2.6.0.&lt;/p&gt;
&lt;p&gt;In other words:
- if you rely on our `source` feature only, &amp;gt;=0.6.6 should be safe,
- if you rely on `libloading`, you must upgrade to 0.8.0 _and_ use their latest DLL &amp;gt;=2.6.0.&lt;/p&gt;
&lt;p&gt;Users handling untrusted video files should update immediately.&lt;/p&gt;</description>
