USN-4099-1: nginx vulnerabilities

Releases

• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

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

Details

Jonathan Looney discovered that nginx incorrectly handled the HTTP/2
implementation. A remote attacker could possibly use this issue to consume
resources, leading to a denial of service.
