Several security issues were fixed in nginx.

Summary

Several security issues were fixed in nginx.

Software Description:

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

Details:

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)
