The DKIM implementation in Exim 4.7x before 4.76 permits matching for DKIM identities to apply to lookup items, instead of only strings, which allows remote attackers to execute arbitrary code or access a filesystem via a crafted identity. La implementación de DKIM en Exim v4.7x con anterioridad a v4.76 permite la comparación de las identidades DKIM para aplicar a las operaciones de búsqueda artículos, en lugar de sólo cadenas, que permite a atacantes remotos ejecutar código arbitrario o acceso a un sistema de ficheros a través de una identidad manipulada. • http://www.debian.org/security/2011/dsa-2236 http://www.securityfocus.com/bid/47836 http://www.ubuntu.com/usn/USN-1135-1 https://lists.exim.org/lurker/message/20110509.091632.daed0206.en.html https://lists.exim.org/lurker/message/20110512.102909.8136175a.en.html • CWE-20: Improper Input Validation •
