USN-3038-1: Apache HTTP Server vulnerability

18 July 2016

A security issue was fixed in the Apache HTTP Server.




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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04
Ubuntu 15.10
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
