Summary
The gst-plugins-good package, used by GStreamer-based media applications, has a flaw in its MOV/MP4 demuxer where it mishandles uncompressed video tracks. A local attacker who gets a user to open a crafted file can trigger an out-of-bounds heap read, which can crash the application and cause a denial of service.

Read the original description
A flaw was found in GStreamer's gst-plugins-good MOV/MP4 demuxer. When processing an uncompressed video track, qtdemux fails to validate the declared row alignment and chroma geometry before using them to build a video buffer layout. A crafted file can cause an out-of-bounds heap read while the sample is copied, potentially crashing the application and causing denial of service.
