Summary
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.
Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
