                Linux-Mandrake Security Update Advisory


Package name:           openssh
Date:                   March 22nd, 2001
Advisory ID:            MDKSA-2001:033

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 2.5.2 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 immediately.


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
http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
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 uprade with "rpm -Uvh package_name".

You can download the updates directly from:
ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates
ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors listed at:

http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.

Please be aware that sometimes it takes the mirrors a few hours to update, so if you want an immediate upgrade, please use one of the two above-listed mirrors.
