3. Problem description:
Rsync is a program for synchronizing files over a network.
Rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot. This could allow a remote attacker to write files outside of the module's "path", depending on the privileges assigned to the rsync daemon. Users not running an rsync daemon, running a read-only daemon, or running a chrooted daemon are not affected by this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0426 to this issue.
Users of Rsync are advised to upgrade to this updated package, which contains a backported patch and is not affected by this issue.
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
