cups bug fix update

Updated cups packages that fix a bug are now available.

The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX(R) operating systems.

These updated packages address the following bug:

* the libcups library, which provides facilities for communicating using
the Internet Printing Protocol (IPP), includes a routine: ippReadIO(). In
the previous version of cups, this routine searched a singly-linked list of
IPP attributes, resulting in serious inefficiency when dealing with large
IPP messages. In environments with a large number of cups printer queues
(2000 or thereabouts), this inefficiency caused gnome-default-printer to
take up to five minutes to go from initial launch to displaying its
"Default Printer" window. In this updated package, ippReadIO() now searches
a doubly-linked list. As a consequnce, in equivalent environments
gnome-default-printer now takes only a few seconds to display its "Default
Printer" window.

All cups users should upgrade to these updated packages, which resolve this
issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
