Package : gst-plugins-ugly1.0 Version : 1.18.4-2+deb11u2 CVE ID : CVE-2026-2920 CVE-2026-2922

Two vulnerabilities were discovered in gst-plugins-ugly1.0, a set of GStreamer plugins from the ugly set.

CVE-2026-2920

The ASF demuxer did not validate the number of streams against the size of its static streams array. A crafted ASF file with more than 32 streams could cause a heap-based buffer overflow and potentially allow code execution.

CVE-2026-2922

The RealMedia demuxer checked for too many video fragments after writing to the fragment storage, allowing an out-of-bounds write.
Additionally, an integer overflow in the fragment size check could bypass the available data validation.

For Debian 11 bullseye, these problems have been fixed in version 1.18.4-2+deb11u2.

We recommend that you upgrade your gst-plugins-ugly1.0 packages.

For the detailed security status of gst-plugins-ugly1.0 please refer to its security tracker page at:
