Gstreamer1-plugins-ugly-free: gstreamer1-plugins-ugly-free: unbounded memory allocation in asfdemux simple index parser

Published Oct 19, 2026 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
Description
A flaw was found in the GStreamer ASF demuxer in gst-plugins-ugly. When parsing a Simple Index object, an attacker-controlled entry count is used to size a heap allocation without being limited to the payload available in the object. Processing a crafted ASF, WMV, or WMA file can cause a very large memory allocation request and lead to denial of service if the allocation fails or the process is memory-constrained.

Remediation

Vendor Workaround

Avoid opening untrusted ASF, WMV, or WMA files in GStreamer-based applications (including local players and media indexers/thumbnailers).
