Date: Fri, 30 Sep 2016 18:00:35 -0000 Reply-To: scientific-linux-users@ Sender: Security Errata for Scientific Linux From: Kevin Hill Subject: Security ERRATA Important: python-twisted-web on SL6.x, SL7.x i386/x86_64 MIME-Version: 1.0 Message-ID: Synopsis: Important: python-twisted-web security update Advisory ID: SLSA-2016:1978-1 Issue Date: 2016-09-29 CVE Numbers: CVE-2016-1000111 -- Security Fix(es): * It was discovered that python-twisted-web 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-2016-1000111) Note: After this update, python-twisted-web will no longer pass the value of the Proxy request header to scripts via the HTTP_PROXY environment variable. -- SL6 x86_64 python-twisted-web-8.2.0-5.el6_8.x86_64.rpm i386 python-twisted-web-8.2.0-5.el6_8.i686.rpm SL7 x86_64 python-twisted-web-12.1.0-5.el7_2.x86_64.rpm - Scientific Linux Development Team lastline .
