September 16, 2024

nginx vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

nginx could be made to crash if it received specially crafted network
traffic.

Software Description:
- nginx: small, powerful, scalable web/proxy server

Details:

It was discovered that the nginx ngx_http_mp4 module incorrectly handled
certain malformed mp4 files. In environments where the mp4 directive is in
use, a remote attacker could possibly use this issue to cause nginx to
crash, resulting in a denial of service.
