Summary: An updated logwatch package that fixes a denial of service issue is now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - noarch Red Hat Linux Advanced Workstation 2.1 - noarch Red Hat Enterprise Linux ES version 2.1 - noarch Red Hat Enterprise Linux WS version 2.1 - noarch 3. Problem description: LogWatch is a customizable log analysis system. LogWatch parses through your system's logs for a given period of time and creates a report analyzing areas that you specify, in as much detail as you require. A bug was found in the logwatch secure script. If an attacker is able to inject an arbitrary string into the /var/log/secure file, it is possible to prevent logwatch from detecting malicious activity. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1061 to this issue. All users of logwatch are advised to upgrade to this updated package, which contain backported fixes 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. 5.
