RHSA-2004:244 - Security Advisory

Topic

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

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.

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.

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:
