Posted by Team   
Mandrake There are several weaknesses in various implementations of the SSH (Secure Shell) protocols.

                Linux-Mandrake Security Update Advisory

Package name:           openssh
Date:                   March 23rd, 2001
Original Advisory Date: March 22nd, 2001
Advisory ID:            MDKSA-2001:033-1

Affected versions:      7.0, 7.1, 7.2, Corporate Server 1.0.1

Problem Description:
 There are several weaknesses in various implementations of the SSH
 (Secure Shell) protocols.  When exploited, they let the attacker obtain
 sensitive information by passively monitoring encrypted SSH sessions.
 The information can later be used to speed up brute-force attacks on
 passwords, including the initial login password and other passwords
 appearing in interactive SSH sessions, such as those used with su.
 Versions of OpenSSH 2.5.0 and later have been fixed to reduce the
 impact of these traffic analysis problems, and as such all Linux-
 Mandrake users are encouraged to upgrade their version of openssh

 In some cases, openssh would disallow logins under Linux-Mandrake 7.0
 and 7.1.  As well, dependency problems have been corrected for 7.0/7.1.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.

To upgrade automatically, use MandrakeUpdate.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".

You can download the updates directly from one of the mirror sites
listed at:

Updated packages are available in the "updates/[ver]/RPMS/" directory.
For example, if you are looking for an updated RPM package for
Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/".  Updated source
RPMs are available as well, but you generally do not need to download

Please be aware that sometimes it takes the mirrors a few hours to
