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.
