Debian 11: DSA-5583-1 Critical: GStreamer Buffer Overflow Threat

A buffer overflow was discovered in the AV1 video plugin for the
GStreamer media framework, which may result in denial of service or
potentially the execution of arbitrary code if a malformed media file
is opened.

The oldstable distribution (bullseye) is not affected.

For the stable distribution (bookworm), this problem has been fixed in
version 1.22.0-4+deb12u4.

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:
