A flaw was 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-2015-6834, CVE-2015-6835, CVE-2015-6836)

A NULL pointer dereference flaw was found in the XSLTProcessor class in PHP. An attacker could use this flaw 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)

As reported upstream, an uninitialized pointer use flaw was found in the phar_make_dirstream() function of PHP's Phar extension. A specially crafted phar file in the ZIP format with a directory entry with a file name '/ZIP' could cause a PHP application function to crash. (CVE-2015-7804)");
