OpenSSH upgrade to the new OpenSSH package immediately.


Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Tue Sep 16 11:13:05 PDT 2003
patches/packages/openssh-3.7p1-i386-1.tgz: Upgraded to openssh-3.7p1.
 From the OpenSSH Security Advisory
 ([link moved to references]):
 'All versions of OpenSSH's sshd prior to 3.7 contain a buffer
 management error. It is uncertain whether this error is
 potentially exploitable, however, we prefer to see bugs
 fixed proactively.'
 (* Security fix *)
