Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/openssh-4.4p1-i486-1_slack10.2.tgz:
Upgraded to openssh-4.4p1.
This fixes a few security related issues. From the release notes found at
[link moved to references]:
* Fix a pre-authentication denial of service found by Tavis Ormandy,
that would cause sshd(8) to spin until the login grace time
expired.
* Fix an unsafe signal handler reported by Mark Dowd. The signal
handler was vulnerable to a race condition that could be exploited
to perform a pre-authentication denial of service. On portable
OpenSSH, this vulnerability could theoretically lead to
pre-authentication remote code execution if GSSAPI authentication
is enabled, but the likelihood of successful exploitation appears
remote.
* On portable OpenSSH, fix a GSSAPI authentication abort that could
be used to determine the validity of usernames on some platforms.

After this upgrade, make sure the permissions on /etc/rc.d/rc.sshd are set
the way you want them. Future upgrades will respect the existing permissions
settings. Thanks to Manuel Reimer for pointing out that upgrading openssh
would enable a previously disabled sshd daemon.
Do better checking of passwd, shadow, and group to avoid adding
redundant entries to these files. Thanks to Menno Duursma.
(* Security fix *)
