Red Hat 7: RHSA-2016:1613-01 Moderate: PHP HTTP Proxy Risk

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ======================================================
An update for php is now available for Red Hat Enterprise Linux 7

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 must be restarted for the update to take effect.

Summary

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
Security Fix(es):
* It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5385)
Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.
Bug Fix(es):
* Previously, an incorrect logic in the SAPI header callback routine caused that the callback counter was not incremented. Consequently, when a script included a header callback, it could terminate unexpectedly with a segmentation fault. With this update, the callback counter is properly managed, and scripts with a header callback implementation work as expected. (BZ#1346758)
