Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5834-1 advisory.

It was discovered that the Apache HTTP Server mod_dav module did not properly handle specially crafted request headers. A remote attacker could possibly use this issue to cause the process to crash, leading to a denial of service. (CVE-2006-20001)

It was discovered that the Apache HTTP Server mod_proxy_ajp module did not properly handle certain invalid Transfer-Encoding headers. A remote attacker could possibly use this issue to perform an HTTP Request Smuggling attack. (CVE-2022-36760)
