also provide increased performance with certain ciphers.

Here are the details from the Slackware 12.0 ChangeLog:
+--------------------------+
patches/packages/openssh-4.7p1-i486-1_slack12.0.tgz:
 Upgraded to openssh-4.7p1.
 From the OpenSSH release notes:
 'Security bugs resolved in this release: Prevent ssh(1) from using a
 trusted X11 cookie if creation of an untrusted cookie fails, found and
 fixed by Jan Pechanec.'
 While it's fair to say that we here at Slackware don't see how this could
 be leveraged to compromise a system, a) the OpenSSH people (who presumably
 understand the code better) characterize this as a security bug, b) it has
 been assigned a CVE entry, and c) OpenSSH is one of the most commonly used
 network daemons. Better safe than sorry.
 More information should appear here eventually:
