An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The JPEG parser reads a segment length value from the bitstream without validating it against available data. A remote attacker could trick a user into opening a specially crafted JPEG file, causing downstream parsing to read beyond the provided input buffer, leading to a crash or potential information disclosure.

    Package        : gst-plugins-bad1.0     CVE ID         : CVE-2026-52718 CVE-2026-52719 CVE-2026-53701

    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+deb13u2.

    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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The     JPEG parser reads a segment length value from the bitstream without validating it against available data.
    A remote attacker could trick a user into opening a specially crafted JPEG file, causing downstream     parsing to read beyond the provided input buffer, leading to a crash or potential information disclosure.
    (CVE-2026-52719)

Note that Nessus relies on the presence of the package as reported by the vendor.
