a patch was released for OS X versions below 10.10 only, so I would assume it should be applied to OS X 10.10: http://support.apple.com/kb/HT6495

I would assume that the patch has already been applied to the shipping final version of 10.10.0; installing system packages designed for older OSX releases sounds dangerous.

Just install a newer bash with homebrew ¯\_(ツ)_/¯

That's what I did, before Apple even released a patch for Mavericks.
