1. Topic:
Updated sysstat packages that fix various bugs and security issues are now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
Sysstat is a tool for gathering system statistics. Isag is a utility for graphically displaying these 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 (cve.mitre.org) has assigned the name CAN-2004-0107 to this issue.
While fixing this issue, a flaw was discovered in the isag utility, which also used insecure temporary file names. A local attacker could overwrite files that the user running isag has write access to using carefully-crafted symbolic links in the /tmp directory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0108 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
* mpstat should work correctly with more than 7 CPUs as well as generate correct statistics when accessing individual CPUs. This issue only affected Red Hat Enterprise Linux 2.1
* The sysstat package was not built with the proper dependencies; therefore, it was possible that isag could not be run because the necessary tools were not available. Therefore, isag was split off into its own subpackage with the required dependencies in place. This issue only
affects Red Hat Enterprise Linux 2.1.
Users of sysstat and isag should upgrade to these updated packages, which contain patches to correct these issues.
NOTE: In order to use isag on Red Hat Enterprise Linux 2.1, you must install the sysstat-isag package after upgrading.
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.
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:
https://rhn.redhat.com/help/latest-up2date.pxt
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
78212 - sysstat package post scripts, trigger scripts use insecure tmp files
90574 - mpstat doesn't report on more than 7 cpus
92052 - sar doesn't seem to handle interface names greater than eight chars
110822 - RHEL 3 U2: iostat -x only returns a small set of the partitions on the system
