Descriptions

Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 does not validate certain Exception objects, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or trigger unintended method execution via crafted serialized data.

Zend/zend_exceptions.c en PHP en versiones anteriores a 5.4.44, 5.5.x en versiones anteriores a 5.5.28 y 5.6.x en versiones anteriores a 5.6.12 no valida ciertos objetos Exception, lo que permite atacantes remotos provocar una denegación del servicio (referencia a puntero NULO y caída de aplicación) o desencadenar la ejecución de un método no previsto a través de datos serializados manipulados.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. The rh-php56 packages provide a recent stable release of PHP with PEAR 1.9.5 and enhanced language features including constant expressions, variadic functions, arguments unpacking, and the interactive debuger. The memcache, mongo, and XDebug extensions are also included. The rh-php56 Software Collection has been upgraded to version 5.6.25, which provides a number of bug fixes and enhancements over the previous version. Security Fixes in the rh-php56-php component have been added.
