yum bug fix update

An updated yum package that fixes several problems and adds an enhancement is
now available for Red Hat Enterprise Linux 5.

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

This update fixes the following bugs:

* Previously, yum checked the configured server host name with the name in the
server's SSL certificate when connecting to HTTPS yum repositories, even when
SSL verification was disabled, which is the default setting. With this update
yum will only check names when SSL verification is enabled. Note: yum-rhn-plugin
always disables name checks even for non-RHN repositories. (BZ#500721)

* Previously, installing obsolete packages resulted in installing the package of
the incorrect arch. With this update, Yum selects the correct arch and the issue
is resolved. (BZ#593349)

* Previously, running yum failed when /proc was not mounted. With this update,
yum uses the generic result instead of trying to narrow down the architecture of
the Central Processing Unit (CPU). (BZ#623955)

* Previously, when getting unique metadata from RHN yum would only delete the
downloaded files and not the generated (.sqlite) files. This meant that
/var/cache/yum would grow without bound. With this update, yum will delete the
generated files as well. (BZ#628963)

* Previously, the yum.conf manual page did not document options for setting SSL
verification parameters for HTTPS yum repositories. With this update, these
options are documented. (BZ#637146)

This update also adds the following enhancement:

* With this update, yum can parse more fields in the updateinfo.xml metadata
and provides these fields to other applications. (BZ#634119)

Yum users are advised to upgrade to this updated package which resolves these
issues.

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

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