                     CVE-2026-59692

    Several vulnerabilities were discovered in gst-plugins-bad1.0, a collection of
    plugins for the GStreamer multimedia framework. Processing specially crafted
    media files or network data could lead to denial of service, disclosure of
    memory contents or potentially arbitrary code execution.

    For Debian 12 bookworm, these problems have been fixed in version
    1.22.0-4+deb12u8.

    We recommend that you upgrade your gst-plugins-bad1.0 packages.
