Unmatched Entries in the root log

Hi,

There are some lines in my root log:

**Unmatched Entries**
Jul 8 13:32:57 MyHost sshd[11828]: Did not receive identification string
from 220.70.115.125.
Jul 8 16:40:41 MyHost sshd[974]: Received signal 15; terminating.
Jul 8 16:42:17 MyHost sshd[974]: Server listening on 0.0.0.0 port 22.

Do I have a security problem in my linux box running sendmail?
Any help will be appreciated.

Jason

It looks like you may be being hit by someone trying to use the sshd
vunerability to gain root access.
