Subject: Security ERRATA Important: httpd on SL5.x, SL6.x i386/x86_64
MIME-Version: 1.0
Message-ID: <20160718210958.20588.63141@slpackages.fnal.gov>

Synopsis: Important: httpd security update
Advisory ID: SLSA-2016:1421-1
Issue Date: 2016-07-18
CVE Numbers: CVE-2016-5387
--

Security Fix(es):

* It was discovered that httpd 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. (CVE-2016-5387)

Note: After this update, httpd will no longer pass the value of the Proxy
request header to scripts via the HTTP_PROXY environment variable.
