RHBA-2010:0045 - cups bug fix update

Synopsis

cups bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated cups packages that fix a severe memory leak in the CUPS scheduler are now available.

Description

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

This update addresses the following issue:

  • when adding or modifying many printer queues, cupsd, the CUPS scheduler leaked memory. For example, running "lpstat" after creating several thousand printer queues caused cupsd to use all available memory, eventually killing other processes and bringing the system down. With this update cupsd no longer leaks memory when adding or modifying large numbers of printer queues and the associated out-of-memory errors and crashes no longer occur. (BZ#552213)

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

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
