- Cfengine is running on this remote host.
-
- cfengine cfservd is reported prone to a remote heap-based buffer
- overrun vulnerability.
-
- The vulnerability presents itself in the cfengine cfservd
- AuthenticationDialogue() function. The issue exists due to a
- lack of sufficient boundary checks performed on challenge data
- that is received from a client.
-
- In addition, cfengine cfservd is reported prone to a remote denial
- of service vulnerability. The vulnerability presents itself in the cfengine
- cfservd AuthenticationDialogue() function which is responsible for processing
- SAUTH commands and also performing RSA based authentication. The vulnerability
- presents itself because return values for several statements within the
- AuthenticationDialogue() function are not checked.
-
- Solution: Upgrade to 2.1.8 or newer
-
- Risk factor : High";
