Debian Security Advisory
DLA-553-1 apache2 -- LTS security update
- Date Reported:
- 20 Jul 2016
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2016-5387.
- More information:
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.
