+ attack detector.

+ </description>
+ <impact type="normal">
+ <p>
+ A remote unauthenticated attacker may be able to trigger excessive CPU
+ usage by sending a pathological SSH message, denying service to other
+ legitimate users or processes.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ The system administrator may disable SSH protocol version 1 in
+ /etc/ssh/sshd_config.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All OpenSSH users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/openssh-4.3_p2-r5"</code>
