Cfengine is running on this remote host. This version is prone to a stack-based buffer overrun vulnerability. An attacker, exploiting this flaw, would need network access to the server as well as the ability to send a crafted transaction packet to the cfservd process. A successful exploitation of this flaw would lead to arbitrary code being executed on the remote machine or a loss of service (DoS).

Upgrade to at least 1.5.3-4, 2.0.8 or most recent 2.1 version.
