-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Caldera International, Inc. Security Advisory Subject: Linux - Local vulnerability in OpenSSH Advisory number: CSSA-2001-042.1 Issue date: 2001, December 14 Cross reference: CSSA-2001-042.0 1. Problem Description This is a revised advisory for the 'UseLogin' vulnerability. The original advisory declared the vulnerability as a remote vulnerability, which is not the case. The vulnerability requires the attacker to have a local account, making it a local vulnerability. The OpenSSH team has reported a vulnerability in the OpenSSH server that allows local users to obtain root privilege if the server has the UseLogin option enabled. This option is off by default on OpenLinux, so a default installation is not vulnerable. We nevertheless recommend to our customers to upgrade to the fixed package. 2. Vulnerable Versions System Package OpenLinux 2.3 not vulnerable OpenLinux eServer 2.3.1 All packages previous to and OpenLinux eBuilder openssh-2.9p2-4 OpenLinux eDesktop 2.4 All packages previous to openssh-2.9p2-4 OpenLinux Server 3.1 All packages previous to openssh-2.9p2-4 OpenLinux Workstation 3.1 All packages previous to openssh-2.9p2-4 3. Solution Workaround Make sure that you do not have the UseLogin option enabled. In /etc/ssh/sshd_config, the UseLogin option should either be commended out, or should be set to "no". The proper solution is to upgrade to the latest packages. 4. OpenLinux 2.3 not vulnerable 5.

F-Secure Not Affected

Updated:  December 11, 2001

Status

Not Affected

Vendor Statement

The F-Secure SSH versions 2.x - 3.x doesn't have UseLogin option, nor any means to use 'login' to perform user session setup. Since environmental variables are set only after we're running on user uid, we don't see other exploits of this sort either. Furthermore, administrator is able to control which environmental variables the client is able to set in ssh daemon config file. The F-Secure SSH 1.x versions don't provide means for the client to set environmental variables on the server. Also, while a valid user is able to set environmental variables on the server via pubkey authentication options, these are actually not set in case of 'UseLogin' and use of 'login' to handle user logon.

Fixing the problem Hewlett-Packard recommends that customers download the RPMs listed in the following Red Hat Security Advisory: http://www.redhat.com/support/errata/RHSA-2001-161.html To install the security advisory RPMs, use the following sequence of commands: 1. If you use the tripwire product, we recommend that you run a a consistency check and fix any violations before installing the security advisory RPM. tripwire --check --interactive 2. Install the advisory RPM from the root account. rpm -F 3. Update the tripwire database tripwire --check --interactive NOTE: The rpm -q command can be used to determine if the product is installed. Hewlett-Packard recommends applying the security advisory fixes to installed packages only. The -F option to the RPM installer will only apply the fix if the package is currently installed on the system.

-----BEGIN PGP SIGNED MESSAGE----- SuSE Security Announcement Package: openssh Announcement-ID: SuSE-SA:2001:045 Date: Thursday, Dec 6th 2001 21:30 MET Affected SuSE versions: 6.4, 7.0, 7.1, 7.2, 7.3 Vulnerability Type: local privilege escalation Severity (1-10): 5 SuSE default package: yes Other affected systems: systems running openssh Content of this advisory: 1) security vulnerability resolved: openssh problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) 1) Re-release of SuSE Security Announcement SuSE-SA:2001:044, brief history, Clarification, new problem fixed, upgrade information. This is a re-release of the SuSE Security Announcement SuSE-SA:2001:044, adding another bugfix for the openssh package as well as more detailed information about the vulnerabilities to prevent misunderstandings. The currently supported SuSE distributions 6.4 and newer come with two implementations of the secure shell protocol: The package names are "ssh" and "openssh". Brief history: In 1998, a vulnerability of the secure shell protocol in version 1 has been discovered and named "crc32 compensation attack". The vulnerability allows an attacker to insert arbitrary sequences into the ssh-1 protocol layer. At that time, an added patch fixed the problem in the ssh implementation (visible in the client-side verbose output of the ssh command (-v): "Installing crc compensation attack detector."). In early 2001, Michal Zalewski discovered that the widely used patch was defective and opened another security hole which is being actively exploited today. SuSE Security announcement SuSE-SA:2001:004, published February 16th 2001, available at *[1], addresses this defective patch, among other issues. Clarification/Apology: Our last openssh security announcement SuSE-SA:2001:044 (*[3]) may falsely lead to assume that the openssh-2.9.9p2 update packages on our ftp server fix the vulnerabilities known as crc32 compensation attack. This is incorrect since the openssh-2.3.0 packages released with SuSE Security announcement SuSE-SA:2000:047 in November 2000, available at *[2], already fixed the mentioned (among other) problems. The release of the openssh-2.9.9p2 update packages obsoletes the openssh-2.3.0 update packages. We explicitly regret the used wording and apologize to the openssh development team, in particular Markus Friedl and Theo De Raadt, and thank them for their excellent work on the project. Scanning utilities that can be found on the internet connect to port 22 of a server and read the version string. It should be noted that the bare knowlege of the secure shell protocol version string does not allow to determine whether a running secure shell daemon is actually vulnerable to the defective fix for the crc32 compensation attack. SuSE security receive dozens of requests about statements if the daemons in use are vulnerable or not. Please see reference *[1]. New problem fixed: This re-release of SuSE Security Announcement SuSE-SA:2001:044 (please see reference *[3] below) adds another patch to the openssh-2.9.9p2 packages: A bug allows a local attacker on the server to specify environment variables that can influence the login process if the "UseLogin" configuration option on the server side is set to "yes". If exploited, the local attacker on the secure shell server can execute arbitrary commands as root. In the default configuration of the package, the UseLogin option is set to "no", which means that the administrator of the server must have set the option to "yes" manually before the bug can be exploited. Users who upgraded their SuSE openssh package before December 6th 2001 should upgrade their package again. Use the command "rpm -q openssh" to see which version/release of the package you have installed, and compare this version with the one as listed below. Upgrade information: You can find out which implementation of the ssh protocol you are using with the command "rpm -qf /usr/bin/ssh". If you use the ssh-1.2.* package, please read Reference *[1]. If you use the openssh-* package, please download the rpm package for your distribution from the URL list below, verify its integrity using the methods as described in section 3) of this security announcement and install the package using the command rpm -Uhv file.rpm where file.rpm is the filename of the package that you have downloaded. References: *[1]: http://www.suse.de/de/support/security/adv004_ssh.txt *[2]: http://www.suse.de/de/support/security/2000_047_openssh_txt.txt *[3]: http://www.suse.de/de/support/security/2001_044_openssh_txt.txt SPECIAL INSTALL INSTRUCTIONS: The sshd secure shell daemon on the server side has to be restarted for the new package to become active. If you are logged on on the console, the simple command "rcsshd restart" should do this for you. If you are logged on via secure shell, you should make sure that you do not terminate the connections that are established through the running secure shell daemon/its children. In this case, kill the daemon after package installation using the command kill -TERM `cat /var/run/sshd.pid` and then restart the daemon with the command /usr/sbin/sshd as root. Then, verify that the login procedure works as before. One of the main changes in the new openssh package is that the file $HOME/.ssh/authorized_keys2 is only read by the server if the file $HOME/.ssh/authorized_keys does not exist and if protocol version 2 is being used. The file $HOME/.ssh/authorized_keys2 can be removed after its contents have been added to $HOME/.ssh/authorized_keys. The two configuration files /etc/ssh/sshd_config (server side) and /etc/ssh/ssh_config (client side) contained in the openssh package do not get overwritten upon installation or upgrade, if you have changed them manually. Instead, the new configuration files are written with a .rpmnew suffix. The defaults as provided in the SuSE package make an effort to establish both convenience as well as security.

While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security@suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig to verify the signature of the package, where is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build@suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to . suse-security-announce@suse.com - SuSE's announce-only mailing list.
