New rsync packages available

New rsync packages are available; these fix a remotely exploitable problem
in the I/O functions. These include the security patch from the recently
released rsync-2.5.2. It is strongly recommended that all users of rsync
upgrade to the fixed
packages.

2002-01-28: There was an error in the original bugfix patch for the
security problem - the new rsync could fail under some circumstances. This
has been fixed in a new build.

rsync is a powerful tool used for mirroring directory structures across
machines. rsync has been found to contain several signed/unsigned bugs in
its I/O functions which are remotely exploitable. A remote user can crash
the rsync server/client and execute code as the user running the rsync
server or client.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0048 to this issue.

All users of rsync should upgrade their packages. In addition rsync server
administrators should consider using the "use chroot", "uid", and "read
only" options, which can significantly reduce the impact of a security
problem in rsync or elsewhere.

Thanks go to Sebastian Krahmer for providing a patch for this vulnerability
and to Andrew Tridgell and Martin Pool for their rapid response.

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.
