DESCRIPTION:
Nobuhiro Ban has reported a vulnerability in Nagios Plugins, which
can be exploited by malicious people to compromise a vulnerable
system.

The vulnerability is caused due to a boundary error within the
"redir()" function in check_http.c when processing HTTP "Location:"
header information. This can be exploited to cause a buffer overflow
by returning an overly long string in the "Location:" header to a
vulnerable system.

Successful exploitation requires that a connection is made to a
malicious web server.
