Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that the Apache HTTP Server incorrectly parsed chunk headers. A remote attacker could possibly use this issue to perform HTTP request smuggling attacks. (CVE-2015-3183)

It was discovered that the Apache HTTP Server incorrectly handled the ap_some_auth_required API. A remote attacker could possibly use this issue to bypass intended access restrictions. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-3185).
