Summary

Cfengine is running on this remote host. Cfengine contains a component, cfd, which serves as a remote-configuration client to cfengine. This version of cfd contains several flaws in the way that it calls syslog(). As a result, trusted hosts and valid users (if access controls are not in place) can cause the vulnerable host to log malicious data which, when logged, can either crash the server or execute arbitrary code on the stack. In the latter case, the code would be executed as the 'root' user.
