Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-34-1)
Summary:	The remote host is missing an update for the 'openssh' package(s) announced via the USN-34-1 advisory.
Description:	Summary: The remote host is missing an update for the 'openssh' package(s) announced via the USN-34-1 advisory. Vulnerability Insight: @Mediaservice.net discovered two information leaks in the OpenSSH server. When using password authentication, an attacker 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 allow root logins over ssh ('PermitRootLogin no'). By measuring the time between login attempts an attacker could check whether a given root password is correct. This allowed determining weak root passwords using a brute force attack. Affected Software/OS: 'openssh' package(s) on Ubuntu 4.10. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
