RHSA-2012:0302-03 -- Redhat cups

Class: PATCHFamily: unix




The Common UNIX Printing System provides a portable printing layer for Linux, UNIX, and similar operating systems. A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch decompression algorithm implementation used by the CUPS GIF image format reader. An attacker could create a malicious GIF image file that, when printed, could possibly cause CUPS to crash or, potentially, execute arbitrary code with the privileges of the "lp" user. This update also fixes the following bugs: * Prior to this update, the "Show Completed Jobs," "Show All Jobs," and "Show Active Jobs" buttons returned results globally across all printers and not the results for the specified printer. With this update, jobs from only the selected printer are shown. * Prior to this update, the code of the serial backend contained a wrong condition. As a consequence, print jobs on the raw print queue could not be canceled. This update modifies the condition in the serial backend code. Now, the user can cancel these print jobs. * Prior to this update, the textonly filter did not work if used as a pipe, for example when the command line did not specify the filename and the number of copies was always 1. This update modifies the condition in the textonly filter. Now, the data are sent to the printer regardless of the number of copies specified. * Prior to this update, the file descriptor count increased until it ran out of resources when the cups daemon was running with enabled Security-Enhanced Linux features. With this update, all resources are allocated only once. * Prior to this update, CUPS incorrectly handled the en_US.ASCII value for the LANG environment variable. As a consequence, the lpadmin, lpstat, and lpinfo binaries failed to write to standard output if using LANG with the value. This update fixes the handling of the en_US.ASCII value and the binaries now write to standard output properly. All users of cups are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the cupsd daemon will be restarted automatically.
