Synopsis: Updated Tripwire packages fix security flaw
Advisory ID: RHSA-2004:244-01
Issue date: 2004-06-14
Updated on: 2004-06-14
Product: Red Hat Enterprise Linux
Cross references:
CVE Names: CAN-2004-0536

1. Topic:

Updated Tripwire packages that fix a format string security vulnerability are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Tripwire is a system integrity assessment tool.

Paul Herman discovered a format string vulnerability in Tripwire version 2.3.1 and earlier. If Tripwire is configured to send reports via email, a local user could gain privileges by creating a carefully crafted file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0536 to this issue.

Users of Tripwire are advised to upgrade to this erratum package which contains a backported security patch to correct this issue. The erratum package also contains some minor bug fixes.

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:


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:
