CentOS 4 : openssh (CESA-2006:0044)

medium Nessus Plugin ID 21975

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated openssh packages that fix bugs in sshd and add auditing of user logins are now available for Red Hat Enterprise Linux 4.

This update has been rated as having low security impact by the Red Hat Security Response Team.

OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. This package includes the core files necessary for both the OpenSSH client and server.

An arbitrary command execution flaw was discovered in the way scp copies files locally. It is possible for a local attacker to create a file with a carefully crafted name that could execute arbitrary commands as the user running scp to copy files locally. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-0225 to this issue.

The following issue has also been fixed in this update :

* If the sshd service was stopped using the sshd init script while the main sshd daemon was not running, the init script would kill other sshd processes, such as the running sessions. For example, this could happen when the 'service sshd stop' command was issued twice.

Additionally, this update implements auditing of user logins through the system audit service.

All users of openssh should upgrade to these updated packages, which resolve these issues.

Solution

Update the affected openssh packages.
