Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : apache2 vulnerability (USN-3038-1) (httpoxy)

Medium Nessus Plugin ID 92409

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that the Apache HTTP Server would set the HTTP_PROXY environment variable based on the contents of the Proxy header from HTTP requests. A remote attacker could possibly use this issue in combination with CGI scripts that honour the HTTP_PROXY variable to redirect outgoing HTTP requests.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected apache2-bin and / or apache2.2-bin packages.
