There's been a vulnerability discovered in SSLv3 that basically allows
attackers to decrypt it. ;(
I would like to apply the following and disable it on our sites for now
until and unless we find a better solution in coming days.
Note that I am likely going to try and test the koji change in stg first
and might adjust it some.
I'll also likely apply this soon anyhow as it's a security issue,
but more eye's +1's welcome.
