Test ID:1.3.6.1.4.1.25623.1.0.882568
Category:CentOS Local Security Checks
Title:CentOS Update for python-twisted-web CESA-2016:1978 centos7
Summary:Check the version of python-twisted-web
Description:Summary:
Check the version of python-twisted-web

Vulnerability Insight:
Twisted is an event-based framework for
internet applications. Twisted Web is a complete web server, aimed at hosting
web applications using Twisted and Python, but fully able to serve static pages
too.

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.

Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.

Affected Software/OS:
python-twisted-web on CentOS 7

Solution:
Please Install the Updated Packages.
