glibc for Red Hat Enterprise Linux Server AUS (v. 6.4)

Hi RedHat team,
With regard to "GHOST: glibc vulnerability (CVE-2015-0235)"
I could not find glibc package for Red Hat Enterprise Linux Server AUS (v. 6.4), which is glibc-2.12-1.107.el6_4.7.x86_64.rpm

[root@REDHAT ~]# rpm -q glibc
glibc-2.12-1.107.el6.x86_64
[root@REDHAT ~]# rpm -q glibc
glibc-2.12-1.107.el6.x86_64
[root@REDHAT ~]# uname -a
Linux REDHAT.mil.hive.com 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

I can only see Red Hat Enterprise Linux Workstation (v. 6) packages, which are listed below:

glibc-2.12-1.149.el6_6.5.x86_64 The GNU libc libraries
glibc-common-2.12-1.149.el6_6.5.x86_64 Common binaries and locale data for glibc

glibc-utils-2.12-1.149.el6_6.5.x86_64 Development utilities from GNU C library

Can I use these instead?
Many thanks
