This is going to have an impact on availability.

The issue has been introduced in 07/11/2013. The weakness was disclosed 02/06/2014 as hevc: check that the VCL NAL types are the same for all slice segments of a frame as confirmed git commit (GIT Repository). The advisory is shared at git.videolan.org. This vulnerability is uniquely identified as CVE-2014-125019. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
