USN34-1 : openssh information leakage |

openssh information leakage Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - openssh-client - openssh-server - ssh - ssh-askpass-gnome Description : @Mediaservice.net discovered two information leaks in the OpenSSH server. When using password authentication, a possible hacker could test whether a login name exists by measuring the time between failed login attempts, i. e. the time after which the "password:" prompt appears again. A similar issue affects systems which do not permit root logins over ssh ("PermitRootLogin no"). By measuring the time between login attempts a possible hacker could check whether a given root password is correct. This permited determining weak root passwords using a brute force attack. Solution : Upgrade to : - openssh-client-3.8.1p1-11ubuntu3.1 (Ubuntu 4.10) - openssh-server-3.8.1p1-11ubuntu3.1 (Ubuntu 4.10) - ssh-3.8.1p1-11ubuntu3.1 (Ubuntu 4.10) - ssh-askpass-gnome-3.8.1p1-11ubuntu3.1 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
