Synopsis :

The remote host is affected by a remote buffer overflow vulnerability.

Description :

Cfengine is running on this remote host.

This version has 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. Successful exploitation of this flaw would lead
to arbitrary code being executed on the remote machine or a loss of
service (DoS).
