CVE-2026-19389
NVD: 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. NVD: Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. NVD: This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed.
