Bug Fix

BZ#854472
Previously, when no authentication was initially provided (or even requested), cups returned the "forbidden" status rather than the correct "unauthorized" status. Consequently, certain operations, such as attempts to move a job between queues using the web user interface, failed. An upstream patch has been provided to address this bug and cups now returns correct status in the described scenario.
All users of cups are advised to upgrade to these updated packages, which fix this bug.
Updated cups packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.

Bug Fix

BZ#873592
Previously, with LDAP browsing enabled, one of the objects used for LDAP queries was freed twice, which caused the cupsd service to terminate unexpectedly with a segmentation fault. Additionally, names of browsed LDAP queues were truncated by a single character. Consequently, only one print queue was listed if multiple print queues with names varying only in the last character were defined. With this update, an upstream patch that resolves these problems has been back-ported, and the cupsd service no longer crashes and LDAP print queues are now displayed correctly.
All users of cups are advised to upgrade to these updated packages, which fix this bug.
Updated cups packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.

Bug Fixes

BZ#738410
Prior to this update, the textonly filter did not always correctly generate output when a single copy was requested. The textonly filter generates output for a single or multiple copies by spooling the output for one copy into a temporary file, then sending the content of that temporary file as many times as required. However, if the filter was used for the MIME-type conversion rather than as a PostScript Printer Description (PPD) filter, and a single copy was requested, the temporary file was not created and the program failed with the "No such file or directory" message. With this update, the textonly filter has been modified to create a temporary file regardless of the number of copies specified. The data is now sent to the printer as expected.
BZ#738914, BZ#740093
Previously, empty jobs could be created using the "lp" command either by submitting an empty file to print (for example by executing "lp /dev/null") or by providing an empty file as standard input. In this way, a job was created but was never processed. With this update, creation of empty print jobs is not allowed, and the user is now informed that no file is in the request.
BZ#806818
The German translation for the search page template of the web interface contained an error that prevented the search feature from functioning correctly: attempting to search for a printer in the CUPS web interface failed, and an error message was displayed in the browser. The bug in the search template has been fixed, and the search feature in the German locale now works as expected in this scenario.
