This host is installed with TOR and is prone to Privilege Escalation vulnerability.
Successful exploitation will let the attacker gain privileges and escalate the privileges in malicious ways.
Upgrade to the latest version 0.2.0.32 http://www.torproject.org/download.html.en
The flaws are due to - an application does not properly drop privileges to the primary groups of the user specified by the User Parameter. - a ClientDNSRejectInternalAddresses configuration option is not always enforced which weaknesses the application security.
Tor version 0.2.0.31 or prior.
