Critical security problem in ImageMagick < 6.3.3-5 - where was this announced?

A critical security bug was recently found in versions of ImageMagick 
before 6.3.3-5.  NIST assigned the bug its highest security rating, and 
claims the flaw "Provides administrator access, Allows complete 
confidentiality, integrity, and availability violation":

I subscribe to both the 'magick-announce' and 'magick-developers' 
mailing list, and have not seen any announcements informing people that 
they need to upgrade or risk having their servers compromised.  Is there 
an official ImageMagick channel for making these types of security 
announcements that I am not aware of?
