RHBA-2010:0210 - Bug Fix Advisory

Topic

Updated cups packages that fix several bugs are now available.

Description

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

These updated packages address the following bugs:

• Landscape orientation jobs had incorrect page margins. This affects all

landscape orientation PDF files, including any landscape job printed from
Mac OS X. (BZ#447987)

• When running PHP files through the scheduler's web interface the wrong

version PHP interpreter was used, causing missing header lines. (BZ#460898)

• The tmpwatch package is needed by cups but there was no package

dependency on it. (BZ#487495)

• There was a memory leak in the scheduler's handling of "file:" device

URIs. (BZ#496008)

• Setting quota limits using the lpadmin command did not work correctly.

(BZ#496082)

• There were several issues with CGI handling in the scheduler, causing

custom CGI scripts not to work as expected. (BZ#497632, BZ#506316)

• The dependencies between the various sub-packages were not made explicit

in the package requirements. (BZ#502205)

• Jobs with multiple files could be removed from a disabled queue when it

is re-enabled. (BZ#506257)

• The cups-lpd daemon, for handling RFC 1179 clients, could fail under load

due to incorrect temporary file handling. (BZ#523152)

• The CUPS PDF input filter is no longer a separate PDF handling

implementation, and instead uses the pdftops program from the poppler-utils
package directly. (BZ#527429)

• Adding or modifying many queues could cause the scheduler to leak large

amounts of memory. (BZ#540646)

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