First step is to check whether you actually have multiple versions of the
same package installed, or just that RPM/Yum think so, ie. does the command:
rpm -q glibc
report one or more packages?
If the former, the you can probably fix the problem by a clean and reset of
both the RPM and Yum package data (which is harmless in any event):
# Remove the RPM package DB:
rm -f /var/lib/rpm/__db.*
# Rebuild the RPM package DB:
rpmdb --rebuilddb
# Clear the Yum cache:
yum clean all
# Rebuild the Yum package data (and check for updates):
yum check-update
If the latter, then try the following:
# Install yum-utils (if you don't have it already):
yum install yum-utils
# Clean up duplicate packages
# NOTE: I'd recommend a review of the Man page and use of the
information options first:
package-cleanup --cleandupes
