SUSE just linked to the git repository's web UI, and remarked there are random 502 errors happening; probably so they're not notified about "broken links".

[edit] From the "<meta name="description">" tag (I noticed the nice slug when I shared the link with a friend):

  Screen is the traditional terminal multiplexer software used on Linux and Unix systems. We found a local root exploit in Screen 5.0.0 affecting Arch Linux and NetBSD, as well as a couple of other issues that partly also affect older Screen versions, which are still found in the majority of distributions.
