CERT Advisory Notice: Clarifications regarding recent vulnerabilities in OpenSSH

The CERT/CC has received queries regarding several recent OpenSSH
vulnerabilities. We are sending this message to help ensure that
administrators have not overlooked one or more of these vulnerabilities.

There have been several recent vulnerabilities affecting OpenSSH. They
are

VU#333628 - OpenSSH contains buffer management errors
http://www.kb.cert.org/vuls/id/333628

This issue addresses two releases of OpenSSH to resolve multiple
issues in the buffer management code. It is unclear if these issues
are exploitable, but they are resolved in version 3.7.1. Note that
there are other additional flaws in the buffer management code as
reported by Openwall GNU/*/Linux in
http://www.kb.cert.org/vuls/id/JARL-5RFQQZ. These four additional
flaws are believed to be relatively minor, and are scheduled to be
included in the next version of OpenSSH.

VU#602204 - OpenSSH PAM challenge authentication failure
http://www.kb.cert.org/vuls/id/602204

Under non-standard configurations, portable versions of OpenSSH 3.7p1
and 3.7.1p1 are vulnerable to a remotely exploitable vulnerability.
Exploitation of this vulnerability may lead to a remote attacker
gaining privileged access to the server, in some cases root access.

VU#209807 - Portable OpenSSH server PAM conversion stack corruption
http://www.kb.cert.org/vuls/id/209807

There is a vulnerability in portable versions of OpenSSH 3.7p1 and
3.7.1p1 that may permit an attacker to corrupt the PAM conversion
stack. The complete impact of this vulnerability is unclear, but may
lead to privilege escalation, or a denial of service.

Please check the vulnerability notes for resolutions and additional
details.

Thank you.
