Stack-based buffer overflow in the parseLegacySyslogMsg function in tools/syslogd.c in rsyslogd in rsyslog 4.6.x before 4.6.8 and 5.2.0 through 5.8.4 might allow remote attackers to cause a denial of service (application exit) via a long TAG in a legacy syslog message. Un desbordamiento de búfer basado en la pila en la función parseLegacySyslogMsg en tools/syslogd.c en rsyslogd en rsyslog v4.6.x antes de v4.6.8 y v5.2.0 hasta la v5.8.4 podría permitir a atacantes remotos provocar una denegación de servicio (salida de la aplicación) a través de un TAG demasiado largo en un mensaje de syslog antiguo. • http://git.adiscon.com/?p=rsyslog.git%3Ba=commit%3Bh=1ca6cc236d1dabf1633238b873fb1c057e52f95e http://lists.fedoraproject.org/pipermail/package-announce/2011-September/065837.html http://lists.fedoraproject.org/pipermail/package-announce/2011-September/065941.html http://lists.opensuse.org/opensuse-updates/2011-09/msg00013.html http://secunia.com/advisories/45922 http://secunia.com/advisories/46027 http://securitytracker.com/id?1026000 http://www.mandriva.com/security/advisories?name=MDVSA-2011:134 http://w • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
