There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video
    stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up
    to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or
    stream that, when processed by a GStreamer-based application, could leak limited memory contents through
    video metadata, potentially exposing sensitive information from the application's address space.
    (CVE-2026-12891)

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21370-1 advisory.

    This update for gstreamer-plugins-bad fixes the following issues

    - CVE-2026-12891: unchecked aspect_ratio_idc value used as an array index in the H.266 parser could cause     a global out-       of-bounds read (bsc#1268872).
    - CVE-2026-12892: 1-byte heap out-of-bounds read in H.264 NAL extension slice parser (bsc#1268971).
    - CVE-2026-14935: webrtcbin accepts remote SDP without a=fingerprint due to inverted presence check     (bsc#1271051).
    - CVE-2026-52720: invalid check of total area instead of individual dimensions could trigger a heap out-     of-bounds write       (bsc#1268406).
    - CVE-2026-52721: crafted PCAP records during IPv4 or TCP header parsing could cause an out-of-bounds read       (bsc#1268408).
    - CVE-2026-52722: crafted VMnc stream with large cursor dimensions can overflow signed integer     (bsc#1268410).
    - CVE-2026-53701: multi-slice-in-tile partitions without slice index bounds checks could trigger an out-     of-bounds write       (bsc#1268172).
    - CVE-2026-53702: incorrect loop bound during H.265 SEI message parsing could result in a stack buffer     overflow       (bsc#1268168).
    - CVE-2026-59692: unvalidated peer certificate Subject DN printed during a DTLS handshake could cause a     stack buffer       overflow (bsc#1271168).

    Multiple security vulnerabilities were discovered in plugins for     the GStreamer media framework and its codecs and demuxers, which     may result in denial of service or potentially the execution of     arbitrary code if a malformed media file is opened.

    For the stable distribution (trixie), these problems have been fixed in     version 1.26.2-3+deb13u3.

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

    For the detailed security status of gst-plugins-bad1.0 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/gst-plugins-bad1.0
