Descriptions

The php_url_parse_ex function in ext/standard/url.c in PHP before 5.5.38 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via vectors involving the smart_str data type.

La función php_url_parse_ex en ext/standard/url.c en PHP en versiones anteriores a 5.5.38 permite a atacantes remotos provocar una denegación de servicio (sobrelectura de buffer) o posiblemente tener otro impacto no especificado a través de vectores que involucran el tipo de datos smart_str.

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.
