Descriptions

Perl-Compatible Regular Expression (PCRE) library before 7.3 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via regex patterns containing unmatched "\Q\E" sequences with orphan "\E" codes.

La biblioteca Perl-Compatible Regular Expression (PCRE) anterior a la versión 7.3 permite a los atacantes dependiendo del contexto causar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario por medio de patrones regex que contienen secuencias incomparables "\Q\E" con códigos huérfanos de "\E".
