Bugzilla Bug 193179

Evil Ninja Squirrel discovered a stack-based buffer overflow in balsa.

According to RedHat:
  A remote IMAP server can overflow a statically sized buffer on stack
  and possible execute arbitrary code with privilegies of user running
  Balsa with a long message name in response to FETCH command of IMAP
  protocol. ( https://bugzilla.redhat.com/297581 )

Gnome, please advise.

I've bumped to balsa 2.3.20.  It seems to work in my minimal testing.  (No one
in the gnome herd actually uses balsa a their mail client.)

Arches, please test and mark stable mail-client/balsa-2.3.20.
Target kewyords are "alpha amd64 ppc sparc x86"
