Title:	Mandrake Security Advisory MDKSA-2002:040 (openssh)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to openssh announced via advisory MDKSA-2002:040. Details of an upcoming OpenSSH vulnerability will be published early next week. According to the OpenSSH team, this remote vulnerability cannot be exploited when sshd is running with privilege separation. The priv separation code is significantly improved in version 3.3 of OpenSSH which was released on June 21st. Unfortunately, there are some known problems with this release compression does not work on all operating systems and the PAM support has not been completed. The OpenSSH team encourages everyone to upgrade to version 3.3 immediately and enable privilege separation. This can be enabled by placing in your /etc/ssh/sshd_config file the following: UsePrivilegeSeparation yes The vulnerability that will be disclosed next week is not fixed in version 3.3 of OpenSSH, however with priv separation enabled, you will not be vulnerable to it. This is because privilege separation uses a seperate non-privileged process to handle most of the work, meaning that any vulnerability in this part of OpenSSH will never lead to a root compromise. Only access as the non-privileged user restricted in chroot would be available. MandrakeSoft encourages all of our users to upgrade to the updated packages immediately. This update creates a new user and group on the system named sshd that is used to run the non-privileged processes. Affected versions: 7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1, Single Network Firewall 7.2 Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you. http://www.securityspace.com/smysecure/catid.html?in=MDKSA-2002:040 http://marc.theaimsgroup.com/?l=openssh-unix-dev&m=102495293705094&w=2 Risk factor : High
