Ubuntu 14.04 LTS / 16.04 LTS : Apache HTTP Server vulnerability (USN-3425-1)

high Nessus Plugin ID 103356

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3425-1 advisory.

 Hanno Bck discovered that the Apache HTTP Server incorrectly handled Limit directives in .htaccess files. In certain configurations, a remote attacker could possibly use this issue to read arbitrary server memory, including sensitive information. This issue is known as Optionsbleed.

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

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

Solution

Update the affected packages.
