Last modified

CVE-2026-19389 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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. EPSS estimates a 0.24% chance of exploitation in the next 30 days.

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.
