Red Hat Security Advisory

Synopsis: Updated OpenSSH packages fix potential vulnerability
Advisory ID: RHSA-2003:279-01
Issue date: 2003-09-16
Updated on: 2003-09-16
Product: Red Hat Linux
Keywords:  
Cross references:  
Obsoletes: RHSA-2003:222
CVE Names: CAN-2003-0693

1. Topic:

Updated OpenSSH packages are now available that fix a bug that may be remotely exploitable.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

OpenSSH is a suite of network connectivity tools that can be used to establish encrypted connections between systems on a network and can provide interactive login sessions and port forwarding, among other functions.

The OpenSSH team has announced a bug which affects the OpenSSH buffer handling code. This bug has the potential of being remotely exploitable.

All users of OpenSSH should immediately apply this update which contains a backported fix for this issue.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:

Red Hat Security Advisory

Synopsis: Updated KDE packages fix security issues
Advisory ID: RHSA-2003:269-01
Issue date: 2003-09-16
Updated on: 2003-09-16
Product: Red Hat Linux
Keywords: PAM pam_krb5 pam_setcred
Cross references:  
Obsoletes: RHSA-2003:235
CVE Names: CAN-2003-0690 CAN-2003-0692

1. Topic:

Updated KDE packages that resolve a local security issue with KDM PAM support and weak session cookie generation are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

KDE is a graphical desktop environment for the X Window System.

KDE between versions 2.2.0 and 3.1.3 inclusive contain a bug in the KDE Display Manager (KDM) when checking the result of a pam_setcred() call. If an error condition is triggered by the installed PAM modules, KDM might grant local root access to any user with valid login credentials.

It has been reported that one way to trigger this bug is by having a certain configuration of the MIT pam_krb5 module that leaves a session alive and gives root access to a regular user. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0690 to this issue.

In addition, the session cookie generation algorithm used by KDM was considered too weak to supply a full 128 bits of entropy. This could make it possible for non-authorized users, who are able to bypass any host restrictions, to brute-force the session cookie and gain acess to the current session. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0692 to this issue.

Users of KDE are advised to upgrade to these erratum packages, which contain security patches correcting these issues.

Red Hat would like to thank the KDE team for notifying us of this issue and providing the security patches.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:

https://rhn.redhat.com/help/latest-up2date.pxt
