[sflack-security] openssh (SFSA:2007-255-01)
New openssh packages are available for Sflack 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:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4752
Here are the details from the Sflack 12.0 ChangeLog:
+--------------------------+
patches/packages/openssh-4.7p1-x86_64-1_sflack12.0.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 Sflack 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:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4752
(* Security fix *)
