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
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
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
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.
