Red Hat Security Advisory Synopsis: Updated licq packages fixing security problems available Advisory ID: RHSA-2001:023-03 Issue date: 2001-02-28 Updated on: 2001-03-22 Product: Red Hat Powertools Keywords: licq buffer overrun system() system Cross references: Obsoletes: - --------------------------------------------------------------------- 1. Topic: Updated Red Hat Powertools 6.2 packages fixing two security problems in licq are available. 2. Relevant releases/architectures: Red Hat Powertools 6.2 - alpha, i386, sparc 3. Problem description: licq as shipped with Red Hat Powertools 6.2 is vulnerable to two security problems: An overrunnable buffer in its logging code, and an unguarded system() call to execute an external browser when receiving an URL. 4. Solution: 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 directly *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.
