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.
