NVD Description

Note: Versions mentioned in the description apply only to the upstream libgstisoff-1_0-0 package and not the libgstisoff-1_0-0 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or stream that, when processed by a GStreamer-based application, could leak limited memory contents through video metadata, potentially exposing sensitive information from the application's address space.
