It seems this is an issue on the *ssl*.rpm packages being installer.
I did this and the update finished in about 5 minutes.
a) Inserted update ISO
b) SSH login
c) Mounted the ISO
mount /dev/cdrom /media/
cd /media/update/package-pool
rpm -Uvh openssl-*
rpm -Uvh libopenssl0_9_8-0.9.8j-0.44.1.x86_64.rpm
rpm -Uvh openssh-5.1p1-41.55.1.x86_64.rpm
umount /media/
d) Do the regular update from DVD.
e) Reboot.
Cheers,
Davi
