Summary

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
A flaw was found in the way the PHP module for the Apache httpd web server handled pipelined requests. A remote attacker could use this flaw to trigger the execution of a PHP script in a deinitialized interpreter, causing it to crash or, possibly, execute arbitrary code. (CVE-2015-3330)
A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. (CVE-2015-4024)
An integer overflow flaw leading to a heap-based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code. (CVE-2015-4022)
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-2015-4602, CVE-2015-4603)
It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2015-4025, CVE-2015-4026, CVE-2015-3411, CVE-2015-3412, CVE-2015-4598)
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-2015-2783, CVE-2015-3307, CVE-2015-3329, CVE-2015-4021)
Multiple flaws were found in PHP's File Information (fileinfo) extension. A remote attacker could cause a PHP application to crash if it used fileinfo to identify type of attacker supplied files. (CVE-2015-4604, CVE-2015-4605)
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.
