[slackware-security] openssh

New openssh packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1,
10.2, and -current to fix security issues.

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

https://vulners.com/cve/CVE-2006-4924
https://vulners.com/cve/CVE-2006-5051
https://vulners.com/cve/CVE-2006-5052

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
http://www.openssh.com/txt/release-4.4:
* 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 hander 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 *)

Where to find the new packages:

HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
from ftp.slackware.com.

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