Descriptions

PCRE before 8.36 mishandles the /((?(R)a|(?1)))+/ pattern and related patterns with certain recursion, which allows remote attackers to cause a denial of service (segmentation fault) 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 8.36 no maneja correctamente el patrón /((?(R)a|(?1)))+/ y patrones relacionados con cierta recursión, lo que permite a atacantes remotos causar una denegación de servicio (fallo de segmentación) 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.
