Debian Security Advisory

DSA-027-1 OpenSSH -- remote exploit

Date Reported:
09 Feb 2001
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:
  1. Versions of OpenSSH prior to 2.3.0 are vulnerable to a remote arbitrary memory overwrite attack which may lead to a root exploit.
  2. 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:

Debian 2.2 (potato)
