Descriptions

The match function in pcre_exec.c in PCRE before 8.37 mishandles the /(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/ pattern and related patterns involving (*ACCEPT), which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (partially initialized memory and application crash) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-2547.

La función match en pcre_exec.c en PCRE en versiones anteriores a 8.37 no maneja correctamente el patrón /(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/ y patrones relacionados que involucran (*ACCEPT), lo que permite a atacantes remotos obtener información sensible de la memoria de proceso o causar una denegación de servicio (memoria parcialmente inicializada y caída de aplicación) a través de una expresión regular manipulada, según lo demostrado por un objeto JavaScript RegExp encontrado por Konqueror, también conocida como ZDI-CAN-2547.
