In remediation of DROWN, I need to update openssl packages on several EL6 servers. SSLv2 was turned off a long time ago but need to get these binaries up to date.
I found that yum update presented the updated openssl binary on two of the machines, but not the third. The repositories on all three machines are identical.
Is there a reason yum would present an update to one box but not the other (assuming again that repo configuration is the same across both machines)?
