Description

An issue was discovered in GStreamer gst-plugins-good before 1.28.2. When parsing MP4 audio tracks, the isomp4 plugin's qtdemux_audio_caps function does not sufficiently validate atom data before performing division operations, leading to denial of service due to integer division by zero.

Affected products

How to fix

Upgrade to a fixed version: GStreamer Good Plug-ins 1.28.2. Check the vendor advisory for mitigations.
