Package        : nginx
CVE ID         : CVE-2021-23017
Debian Bug     : 989095

Luis Merino, Markus Vervier and Eric Sesterhenn discovered an off-by-one
in Nginx, a high-performance web and reverse proxy server, which could
result in denial of service and potentially the execution of arbitrary
code.

For the stable distribution (buster), this problem has been fixed in
version 1.14.2-2+deb10u4.

We recommend that you upgrade your nginx packages.

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