Summary
The GStreamer multimedia framework's H.265 (HEVC) parser, in the gst-plugins-bad package, can be made to use uninitialized memory when a video parameter set declares more than one HRD parameter set. An attacker can reach it remotely, without logging in, by supplying a crafted H.265 file or stream that a victim opens, and the result is unpredictable parser behavior that may crash the application, causing denial of service.

Read the original description
A flaw was found in GStreamer's gst-plugins-bad package. A use of uninitialized memory vulnerability exists in the H.265 (HEVC) bitstream parser when processing Video Parameter Sets that declare more than one HRD (Hypothetical Reference Decoder) parameter set. A remote attacker could exploit this by providing a crafted H.265 media file or stream that, when processed by an application using GStreamer, causes unpredictable parser behavior and may crash the application. This can lead to a denial of service for any application using GStreamer to play back H.265 content.
