Kerentanan Out-of-bounds Read pada gstreamer, redhat enterprise linux. Skor CVSS 3.1 4.3 (Medium) menurut redhat.com.

Deskripsi (NVD)

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.
