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 plugin. Applications explicitly using mpegpsdemux or rsndvdbin should avoid processing untrusted MPEG Program Stream or DVD input until fixed packages are available. These mitigations disable affected playback paths but are not complete fixes. Fixed versions are available in newer releases such as RHEL 10.4 and Fedora 44. Users should apply updates when available.
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 parsing 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 sufficiently check remaining data before reading timestamps and optional header fields. The vulnerability requires a user or media-processing pipeline to open a malicious file. No information disclosure or integrity impact has been demonstrated. Mitigations include disabling the affected MPEG Program Stream demuxer plugin until a fixed package is available.
