                     CVE-2026-88914

    Multiple vulnerabilities were discovered in gst-plugins-good1.0, a collection
    of plugins for the GStreamer multimedia framework. Processing specially
    crafted media files or RTP streams could result in denial of service,
    disclosure of information or execution of arbitrary code.

    For Debian 12 bookworm, these problems have been fixed in version
    1.22.0-5+deb12u4.

    We recommend that you upgrade your gst-plugins-good1.0 packages.
