high Nessus Plugin ID 85042

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2686-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
