Summary
Summary
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 overwritesystem files using carefully-crafted symbolic links in the /tmp directory.The Common Vulnerabilities and Exposures project (cve.mitre.org) hasassigned 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 of1024)* sar should handle network device names with more than 8 characters properlyUsers of sysstat should upgrade to these updated packages, whichcontain patches to correct these issues.
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:
