Descriptions
The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
La función pcre_compile en pcre_compile.c en PCRE en versiones anteriores a 8.38 no maneja correctamente cierta anidación [: , lo que permite a atacantes remotos causar una denegación de servicio (consumo de CPU) 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.
