Affected Packages:

ssh

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 2344.
In Mitre's CVE dictionary: CVE-2001-0361.

More information:

Versions of OpenSSH prior to 2.3.0 are vulnerable to a remote arbitrary memory overwrite attack which may lead to a root exploit.
CORE-SDI has described a problem with regards to RSA key exchange and a Bleichenbacher attack to gather the session key from an ssh session.

Both of these issues have been corrected in our ssh package 1.2.3-9.2. We recommend you upgrade your openssh package immediately.

Fixed in:
