RHEA-2009:0201 - Product Enhancement Advisory

Topic

New cups packages are now available.

Description

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

This update addresses the following issues:

• The log files were executable.
• A warning message about a deprecated configuration setting was misleading.
• File permissions were incorrect for the classes.conf configuration file.
• The scheduler could hang when printing a job to a remote class.
• The cache of remote queues would be loaded even when browsing was disabled.
• The automatic MIME type classification of job files could incorrectly

mis-identify files with PJL headers exceeding 2048 bytes.

• cupsaddsmb did not track OrderDependencies and caused collisions in PPD

files.

• User-defined printer and job policies were loaded correctly.
• Jobs with multiple files were handled incorrectly when (a) the job is

paused and resumed, or (b) the job is sent onward to another CUPS server

• The man page for the cancel command was not available.
• Moving jobs failed due to (a) a policy implementation problem, and (b) a

bug in the lpmove command.

• The libcups library could busy-loop during an IPP communication.
• The main cups package did not place strict enough requirements on the

version and release of the cups-libs package.

• During compilation of the code, strict-aliasing warnings were issued.
• The number of simultaneous clients was limited to 1/3 of the file

descriptor limit for the select() system call (1024).

• Multi-part jobs sent between CUPS servers did not function correctly in

all cases.

• Kerberos support has been added.
• When using the CUPS web interface via an https: URL with Firefox 3, the

browser stalled waiting for data.

To fix these problems any many others, the cups package has been upgraded
to 1.3.7.

Users should upgrade to this updated package, which resolves these issues.
