is there a security issue on CentOS 5.3 with openssh 4.3?
If this is a real zero-day exploit.. then yes, there is an issue. The following link may be the best source of information at the moment:

FWIW, I think the second comment about RHEL/Centos in the referenced post is a little off-base. After all, you have to know that a bug exists before you can fix it.
This link[1] seems to show a RHEL 5.3 machine being exploited (could be wrong though). Not sure which version of the openssh-server package it is however beyond the base 4.3.
And a post[2] by a RH engineer to the openssh list.
