Description
==========
Sebastian Krahmer of the SuSE security team discovered a buffer
overflow vulnerability in the handling of a negative HTTP
Content-Length header.

Impact

A buffer overflow in Nagios CGI scripts under certain web serversallows remote attackers to execute arbitrary code via a negative
content length HTTP header.

Workaround
