An update for php is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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)
