Specifically ... I am looking at the httpd and python and pyexpat used 
in CentOS 4 ... I get this:

=====
[root at v20z-x86-64 ~]# python
Python 2.3.4 (#1, Dec 11 2007, 05:28:55)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import pyexpat

 >>> pyexpat.version_info
(1, 95, 7)
=====
[root at v20z-x86-64 ~]# ldd /usr/sbin/httpd | grep expat
         libexpat.so.0 => /usr/lib64/libexpat.so.0 (0x0000002a95dba000)

[root at v20z-x86-64 ~]# strings /usr/lib64/libexpat.so.0 | grep expat_
expat_1.95.7
=====

So, it does not seem that Apache or Python or pyexpat that comes 
standard in CentOS-4 has this issue.
