Descriptions
PCRE before 8.38 mishandles certain repeated conditional groups, which allows remote attackers to cause a denial of service (buffer 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 ciertos grupos condicionales repetidos, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de buffer) 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.
