Releases

• Ubuntu 16.04 ESM
• Ubuntu 15.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• apache2 - Apache HTTP server

Details

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

• apache2-bin - 2.4.18-2ubuntu3.1

Ubuntu 15.10

• apache2-bin - 2.4.12-2ubuntu2.1

Ubuntu 14.04

• apache2.2-bin - 2.4.7-1ubuntu4.13

Ubuntu 12.04

• apache2.2-bin - 2.2.22-1ubuntu1.11

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