CVE-2013-4854 – ISC BIND rdata Denial Of Service Vulnerability

https://notcve.org/view.php?id=CVE-2013-4854

The RFC 5011 implementation in rdata.c in ISC BIND 9.7.x and 9.8.x before 9.8.5-P2, 9.8.6b1, 9.9.x before 9.9.3-P2, and 9.9.4b1, and DNSco BIND 9.9.3-S1 before 9.9.3-S1-P1 and 9.9.4-S1b1, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query with a malformed RDATA section that is not properly handled during construction of a log message, as exploited in the wild in July 2013. La implementación RFC en rdata.c en ISC BIND 9.7.x y 9.8.x anterior a 9.8.5-P2, 9.8.6b1, 9.9.x anterior a 9.9.3-P2, y 9.9.4b1, y DNSco BIND 9.9.3-S1 anterior a 9.9.3-S1-P1 y 9.9.4-S1b1, permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de una petición con una sección RDATA manipulada que se maneja adecuadamente durante la contrucción de mensaje de log. Ha sido explotada "in the wild" en Julio de 2013. This vulnerability allows remote attackers to cause a denial of service condition on vulnerable installations of ISC BIND. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of an rdata section with a length that is less than four. • http://archives.neohapsis.com/archives/bugtraq/2013-08/0030.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://linux.oracle.com/errata/ELSA-2014-1244 http://lists.fedoraproject.org/pipermail/package-announce/2013-August/113108.html http://lists.fedoraproject.org/pipermail/package-announce/2013-August/113251.html http://lists.opensuse.org/opensuse-security-announce/2013-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2013-08/msg00018.html http://rhn. •
