Description

An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The JPEG parser reads a segment length value from the bitstream without validating it against available data. A remote attacker could trick a user into opening a specially crafted JPEG file, causing downstream parsing to read beyond the provided input buffer, leading to a crash or potential information disclosure.
