Red Hat Security Advisory Synopsis: Updated Mailman packages available Advisory ID: RHSA-2001:170-06 Issue date: 2001-12-11 Updated on: 2002-01-02 Product: Red Hat Secure Web Server Keywords: cross-site scripting Cross references: RHSA-2001:168 RHSA-2001:169 Obsoletes: - --------------------------------------------------------------------- 1. Topic: Updated Mailman packages are now available for Red Hat Secure Web Server 3.2 (U.S.). These updates fix cross-site scripting bugs which might allow another server to be used to gain a user's private information from a server running Mailman. 2. Relevant releases/architectures: Red Hat Secure Web Server 3.2 - i386 3. Problem description: A server running Mailmain versions prior to 2.0.8 will send certain user-modifiable data to clients without escaping embedded tags. This data may contain scripts which will then be executed by an unwary client, possibly transmitting private information to a third party. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2001-0884 to 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. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 6.
