RedHat: RHSA-2016-1421:01 Important: httpd security update
Summary
The httpd packages provide the Apache HTTP Server, a powerful, efficient,
and extensible web server.
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.
Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.
Summary
Solution
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the updated packages, the httpd daemon will be restarted
automatically.
