Synopsis

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

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3627-2 advisory.

 Original advisory details:

 Alex Nichols and Jakob Hirsch discovered that the Apache HTTP Server

 mod_authnz_ldap module incorrectly handled missing charset encoding

 headers. A remote attacker could possibly use this issue to cause the

 server to crash, resulting in a denial of service. (CVE-2017-15710)

 Elar Lang discovered that the Apache HTTP Server incorrectly handled

 certain characters specified in <FilesMatch>. A remote attacker could

 possibly use this issue to upload certain files, contrary to expectations.

 incorrectly handled certain headers. A remote attacker could possibly use

 this issue to influence session data. (CVE-2018-1283)
