Descriptions

The phar_convert_to_other function in ext/phar/phar_object.c in PHP before 5.4.43, 5.5.x before 5.5.27, and 5.6.x before 5.6.11 does not validate a file pointer before a close operation, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted TAR archive that is mishandled in a Phar::convertToData call.

La función phar_convert_to_other en ext/phar_objetc.c en PHP en versiones anteriores a 5.4.43, 5.5.x en versiones anteriores a 5.5.27 y 5.6.x en versiones anteriores a 5.6.11 no valida un apuntador de archivo antes de una operación de cierre, lo que permite a atacantes remotos provocar una denegación de servicio (fallo de segmentación) o tener un posible impacto no especificado a través de un archivo TAR manipulado que no es correctamente manejado en una llamada Phar::convertToData.

A flaw was 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.
