Updated yum packages that fix one bug are now available for Red Hat Enterprise Linux 5.
Yum is a command-line utility that allows the user to check for updates and automatically download and install updated RPM packages. Yum automatically obtains and downloads dependencies, prompting the user for permission as necessary.
After having installed a 64-bit package and running the "yum localupdate" command with the same package for both 64-bit and 32-bit architectures, yum installed the 32-bit package if the file list contained the current package versions. With this update, yum now checks for the matching package name and architecture in this scenario; if either the name or architecture does not match, yum does not perform any action.
All users of yum are advised to upgrade to these updated packages, which fix this bug.
