[Security Announce] [ MDKSA-2006:034 ] - Updated openssh packages fix vulnerability
Posted by Bob on: 02/06/2006 11:32 PM [ Print | 0 comment(s) ]
The Mandriva Security Team published a new security update for Mandriva Linux. Here the announcement:

Mandriva Linux Security Advisory MDKSA-2006:034
http://www.mandriva.com/security/
_______________________________________________________________________
Package : openssh
Date : February 6, 2006
Affected: 10.1, 10.2, 2006.0, Corporate 3.0, Multi Network Firewall 2.0
_______________________________________________________________________
Problem Description:
A flaw was discovered in the scp local-to-local copy implementation
where filenames that contain shell metacharacters or spaces are
expanded twice, which could lead to the execution of arbitrary
commands if a local user could be tricked into a scp'ing a specially
crafted filename.
The provided updates bump the OpenSSH version to the latest release
version of 4.3p1. A number of differences exist, primarily dealing
with PAM authentication over the version included in Corporate 3.0
and MNF2. In particular, the default sshd_config now only accepts
protocol 2 connections and UsePAM is now disabled by default.
On systems using alternate authentication methods (ie. LDAP) that use
the PAM stack for authentication, you will need to enable UsePAM.
Note that the default /etc/pam.d/sshd file has also been modified to
use the pam_listfile.so module which will deny access to any users
listed in /etc/ssh/denyusers (by default, this is only the root user).
This is required to preserve the expected behaviour when using
"PermitRootLogin without-password"; otherwise it would still be possible
to obtain a login prompt and login without using keys.
Mandriva Linux 10.1 and newer already have these changes in their
shipped versions. There are new features in OpenSSH and users are
encouraged to review the new sshd_config and ssh_config files when
upgrading.
