Descriptions

The php_wddx_process_data function in ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before 7.0.10 allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via an invalid ISO 8601 time value, as demonstrated by a wddx_deserialize call that mishandles a dateTime element in a wddxPacket XML document.

La función php_wddx_process_data en ext/wddx/wddx.c en PHP en versiones anteriores a 5.6.25 y 7.x en versiones anteriores a 7.0.10 permite a atacantes remotos provocar una denegación de servicio (error de segmentación) o tener otro posible impacto no especificado a través de un valor de tiempo ISO 8601 no válido, según lo demostrado mediante una llamada wddx_deserialize que no maneja adecuadamente un elemento dateTime en un documento XML wddxPacket.

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.
