Summary
nginx vulnerability
Details

It was discovered that nginx incorrectly handled when multiple server blocks are configured to share the same IP address and port. An attacker could use this issue to use session resumption to bypass client certificate authentication requirements on these servers. This issue only affected Ubuntu 24.10.

A buffer overflow and a null pointer deref was fixed in nginx rtmp module (#LP 1977718). This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
