AI-suggested
Red Hat advises setting the environment variable GST_PLUGIN_FEATURE_RANK=mpegpsdemux:NONE in affected processes to prevent automatic selection of the vulnerable MPEG Program Stream demuxer. Applications explicitly using the vulnerable plugins should avoid processing untrusted MPEG Program Stream or DVD input until a fixed package is available. These mitigations disable affected playback paths but are not complete fixes. Users should apply vendor patches when released. Some Red Hat Enterprise Linux versions have fixes deferred under the Moderate policy; check vendor advisories for updates.
Description
A vulnerability in GStreamer's gst-plugins-bad MPEG Program Stream demuxer and resindvd DVD-playback plugin allows an out-of-bounds read when processing specially crafted MPEG Program Stream files. This can cause the application to crash, resulting in a denial of service. The flaw arises because the PES header parsers do not adequately verify the remaining data before reading timestamps and optional header fields. The vulnerability requires user interaction to open or initiate playback of a crafted file and does not impact confidentiality or integrity.
