3. Description:

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server.

Multiple flaws were discovered in the way PHP performed object
unserialization. Specially crafted input processed by the unserialize()
function could cause a PHP application to crash or, possibly, execute
arbitrary code. (CVE-2015-6831, CVE-2015-6832, CVE-2015-6834,
CVE-2015-6835, CVE-2015-6836)

Multiple flaws were found in the way the way PHP’s Phar extension parsed
Phar archives. A specially crafted archive could cause PHP to crash or,
possibly, execute arbitrary code when opened. (CVE-2015-5589,
CVE-2015-5590, CVE-2015-6833, CVE-2015-7803, CVE-2015-7804)

Two NULL pointer dereference flaws were found in the XSLTProcessor class in
PHP. An attacker could use these flaws to cause a PHP application to crash
if it performed Extensible Stylesheet Language (XSL) transformations using
untrusted XSLT files and allowed the use of PHP functions to be used as
XSLT functions within XSL stylesheets. (CVE-2015-6837, CVE-2015-6838)

All rh-php56-php users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After installing
the updated packages, the httpd24-httpd service must be restarted for the
update to take effect.
