Fedora Legacy Update Advisory

Synopsis: Updated sysstat packages fix security vulnerabilities
Advisory ID: FLSA:1372
Issue date: 2004-10-03
Product: Red Hat Linux
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1372
CVE Names: CAN-2004-0107
------------------------------------------------------------------------


------------------------------------------------------------------------
1. Topic:

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

Sysstat is a tool for gathering system statistics.

2. Relevent releases/architectures:

Red Hat Linux 7.3 - i386

3. Problem description:

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 (cve.mitre.org) 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get.
