openssh (SSA:2007-255-01)
Posted on: 09/13/2007 09:05 AM

New openssh packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, 11.0, and 12.0 to fix a possible security issue. This version should also provide increased performance with certain ciphers.

More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 12.0 ChangeLog:
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:
(* Security fix *)

HINT: Getting slow download speeds from
Give a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from

Thanks to the friendly folks at the OSU Open Source Lab
( for donating additional FTP and rsync hosting
to the Slackware project! :-)
