Descriptions
PCRE before 8.38 mishandles the /(?J)(?'d'(?'d'\g{d}))/ pattern and related patterns with certain recursive back references, 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, a related issue to CVE-2015-8392 and CVE-2015-8395.
PCRE en versiones anteriores a 8.38 no maneja correctamente el patrón /(?J)(?'d'(?'d'\g{d}))/ y patrones relacionados con ciertas referencias hacia atrás recursivas, 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, un problema relacionado con CVE-2015-8392 y CVE-2015-8395.
