FFmpeg · Ffmpeg · CVE-2017-1000460
**Name of the Vulnerable Software and Affected Versions**
libav version 13 dev0
ffmpeg version n3.4
chromium versions prior to 56 (before Feb 13, 2017)
**Description**
The issue arises from the return value of `init get bits` being ignored, leading to `get ue golomb(&gb)` being called on an uninitialized `get bits` context. This results in a NULL deref exception.
**Recommendations**
For libav version 13 dev0, ensure proper initialization of the `get bits` context before calling `get ue golomb(&gb)`.
For ffmpeg version n3.4, verify the return value of `init get bits` to prevent calling `get ue golomb(&gb)` on an uninitialized context.
For chromium versions prior to 56 (before Feb 13, 2017), update to a version released after Feb 13, 2017, to ensure the issue is resolved.
