A flaw was found in gst-plugins-base. A heap buffer overflow can be triggered when processing video buffers whose attached GstVideoMeta metadata declares plane strides and offsets that exceed the actual backing memory allocation. The metadata is not range-checked during deserialization, and the video frame mapping code does not verify that the declared plane geometry fits within the buffer before allowing consumers to read or write video data. A local attacker who controls the sending side of a GStreamer inter-process IPC pipeline can deliver a crafted buffer carrying fabricated strides, causing the receiving process to read or write beyond heap boundaries. Successful exploitation can cause a denial of service or potentially allow code execution within the affected process.

The remote Fedora 45 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-b1f189a5b6 advisory.

    Update to gstreamer-1.28.8.


Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 44 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-343461e9d1 advisory.

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the bfa621d9-e508-4e3e-9a15-c2b54929ea77 advisory.

    The GStreamer project reports:
    Multiple security issues were identified and fixed in the GStreamer framework.
