yum bug fix update

An updated yum package that resolves an issue with RHN Snapshot Rollback is
now available.

Yum is a utility that can check for or automatically download and install
updated RPM packages. Dependencies are obtained and downloaded
automatically prompting the user as necessary.

This updated yum package fixes the following bug:

* attempting to roll back a system to a previous configuration by selecting
the "Rollback to Snapshot" function on the RHN System Details page could
cause the removal of packages which should have been downgraded instead.
With this updated package, this situation is now handled gracefully, and
packages are correctly downgraded in accordance with the rollback package
manifest. (BZ#503944)

All users of yum and Red Hat Network are advised to upgrade to this updated
package, which resolves this issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
