timed daemon remote denial of service
| timed-remote-dos (6228) |  Medium Risk |
Description:
Timed is vulnerable to a denial of service attack. In systems where the timed daemon has been configured to run, a remote attacker can send malformed packets to the timed daemon to cause the service to crash. The service must be restarted to regain normal functionality.
