This is a pretty coordinated release, I think the ubuntu security team probably has packages ready to be released. The security repository should have the update right away.
Yep. Normally the security embargo for these things covers a large range of distributions and packaging organizations; Ubuntu should be one of them.
Thank you both!
Had quite a few packages updated on my Ubuntu servers today and believed it was this issue. But seeing this is still embargoed it looks like these weren't updates for this problem? Or is Ubuntu releasing binaries but keeping the sources embargoed?
