Descriptions

Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow that allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code.

La biblioteca Perl-Compatible Regular Expression (PCRE) anterior a la versión 7.0 no calcula apropiadamente los tamaños de las "multiple forms of character class" no especificadas, lo que desencadena un desbordamiento de búfer que permite a los atacantes dependiendo del contexto provocar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario.
