When I read this I read that it is fixed in
glibc-2.12-1.149.el6_6.5.src.rpm (RHEL 6), on my CentOS 6 I have according
to " rpm -qi glibc": glibc-2.12-1.149.el6_6.4.src.rpm (which resembles
what is latest on public mirror I maintain, and I checked randomly a
couple of other mirrors - the same). If I read numbers correctly, we all
are one minor (very minor ;-) number behind RHEL.

And when I check the machine with
(fully updated CentOS 6) indeed the program from section 4 of openwall
page above says "vulnerable".

Am I the only one (read: an idiot ;-) or others have the same?

Thanks Peter!
