newer versions of openSSH for SLES 11sp2?

Hi all,

I just built two new SLES 11sp2 servers and both of them have several vulnerabilities related to openSSH found by our Nessus scans. The fix to the problems is to upgrade to openSSH 5.9 or greater. The current version on the server is 5.1 and there are no later versions found in the novell repositories.

the latest version available from is 6.1. If I was to install one of these later versions, how would it affect future updates from Novell. For example, if they later release an SP3 for SLES 11, would it overwrite the version of openssh I manually installed?

Thanks for the advice,

What are the vulnerabilities Nessus reports? I would imagine they are
false positives.

Fixes (esp security related) are backported to the SLE versions. Do you
get update notification emails?

If the fixes are backported to the current SLES versions, then how can Nessus be reporting false positives? I guess I don’t understand that part. And no, I don’t get update notification emails.

A lot of tools just check version numbers so whilst the version may be
older, fixes are actually in there and have been backported.
