nagios3 - security update

A stack-based buffer overflow in the cmd_submitf function in cgi/cmd.c
in Nagios, a monitoring and management system for hosts, services and
networks, allowed remote attackers to cause a denial of service
(segmentation fault) via a long message to cmd.cgi.

For Debian 7 Wheezy, this problem has been fixed in version
3.4.1-3+deb7u2.

We recommend that you upgrade your nagios3 packages.
