Thanks you so much Peter.

I thought it is fixed in latest centos rpm.

CVE-2010-3847 is fixed in 2.5-49.el5_5.6 CVE-2010-3856 has no released fix (afaik): http://seclists.org/fulldisclosure/2010/Oct/344

I got "custom packaged of glibc" from a third party(which I know as reliable) site.

Do you have any information about availability of a patched replacement at this time?

Nope
