[***** Start Red Hat Advisory RHSA-2004:020-02 *****] Updated mailman packages close cross-site scripting vulnerabilities Advisory: RHSA-2004:020-02 Last updated on: 2004-02-05 Affected Products: Red Hat Linux 9 CVEs (cve.mitre.org): CAN-2003-0965 CAN-2003-0992 Security Advisory Details: Updated mailman packages that close various cross-site scripting vulnerabilities are now available. Mailman is a mailing list manager. Dirk Mueller discovered a cross-site scripting bug in the admin interface in versions of Mailman 2.1 before 2.1.4. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0965 to this issue. A cross-site scripting bug in the 'create' CGI script affects versions of Mailman 2.1 before 2.1.3. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0992 to this issue. Users of Mailman are advised to upgrade to the erratum packages, which include backported security fixes and are not vulnerable to these issues. Updated packages: Red Hat Linux 9 ----------------------------------------------------------------------------- SRPMS: mailman-2.1.1-5.src.rpm [ via FTP ] [ via HTTP ] 40acda00aa52b23dbb068cd0bf48d898 i386: mailman-2.1.1-5.i386.rpm [ via FTP ] [ via HTTP ] 6efb83ea4e0658457ca3dd883f4d533d 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.
