Descriptions
The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive.
La función phar_parse_tarfile en ext/phar/tar.c en PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 no verifica que el primer caracter de un nombre de fichero es diferente al caracter \0, lo que permite a atacantes remotos causar una denegación de servicio (desbordamientos de enteros y corrupción de memoria) a través de una entrada manipulada en un archivo tar.
An integer underflow flaw leading to out-of-bounds memory access was found in 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.
