This is because Centos 5 is deprecated and requires manual update of the Base repo file to point everything to the Centos vault.

Source: http://realtechtalk.com/Centos_59_Working_Vault_Repo_file-1921-articles

Backup your /etc/yum.repos.d/Centos-Base.repo

Replace with the following will get you going again:

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
