The remote host is missing updates announced in
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 CVE-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
CVE-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
* 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.
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
