Descriptions
The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \01 string, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
La función pcre_exec en pcre_exec.c en PCRE en versiones anteriores a 8.38 no maneja correctamente un patrón // con una cadena \01, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de buffer basado en memoria dinámica) 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.
It was discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service, or possibly execute arbitrary code.
