Gstreamer: gstreamer1-plugins-ugly-free: gstreamer: integer overflow/underflow in asfdemux bounds checks leading to out-of-bounds read

AI Analysis

No AI analysis yet.

Description

Multiple integer overflow and underflow vulnerabilities were found in the GStreamer gst-plugins-ugly ASF demuxer (asfdemux) when parsing header objects from crafted ASF, WMV, or WMA files. Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed.
