Descriptions

PCRE before 8.38 mishandles (?123) subroutine calls and related subroutine calls, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

PCRE en versiones anteriores a 8.38 no maneja correctamente las llamadas de subrutina (?123) y las llamadas de subrutina relacionadas, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de entero) o posiblemente tener otro impacto no especificado a través de una expresión regular manipulada, según lo demostrado por un objeto JavaScript RegExp encontrado por Konqueror.
