Debian DLA-553-1 : apache2 security update (httpoxy)

Medium Nessus Plugin ID 92474

Synopsis

The remote Debian host is missing a security update.

Description

Scott Geary of VendHQ discovered that the Apache HTTPD server used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request.

For Debian 7 'Wheezy', this problem has been fixed in version 2.2.22-13+deb7u7.

We recommend that you upgrade your apache2 packages.

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

Solution

Upgrade the affected packages.
