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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 ESM

Several security issues were fixed in nginx.

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


It was discovered that nginx incorrectly handled certain memory operations in
the ngx_http_mp4_module module. A local attacker could possibly use this issue
with a specially crafted mp4 file to cause nginx to crash, stop responding, or
access arbitrary memory. (CVE-2022-41741, CVE-2022-41742)
