- --------------------------------------------------------------------- Red Hat Security Advisory

Synopsis: Updated sysstat packages fix security vulnerabilities Advisory ID: RHSA-2004:093-01 Issue date: 2004-03-10 Updated on: 2004-03-10 Product: Red Hat Linux Keywords: Cross references: Obsoletes: CVE Names: CAN-2004-0107 - ---------------------------------------------------------------------

1. Topic:

Updated sysstat packages that fix various bugs and a minor security issue are now available.

2. Relevant releases/architectures:

Red Hat Linux 9 - i386

3. Problem description:

Sysstat is a tool for gathering system statistics.

A bug was found in the Red Hat sysstat package post and trigger scripts, which used insecure temporary file names. A local attacker could overwrite system files using carefully-crafted symbolic links in the /tmp directory. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0107 to this issue.

Other issues addressed in this advisory include:

* iostat -x should return all partitions on the system (up to a maximum of 1024)

* sar should handle network device names with more than 8 characters properly

Users of sysstat should upgrade to these updated packages, which contain patches to correct these issues.

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:

Red Hat Linux 9:
