Package : nginx
CVE ID : CVE-2022-41741 CVE-2022-41742

It was discovered that parsing errors in the mp4 module of Nginx, a
high-performance web and reverse proxy server, could result in denial
of service, memory disclosure or potentially the execution of arbitrary
code when processing a malformed mp4 file.

This module is only enabled in the nginx-extras binary package.

For the stable distribution (bullseye), these problems have been fixed in
version 1.18.0-6.1+deb11u3.

We recommend that you upgrade your nginx packages.
