Updated cups packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX operating systems.
A use-after-free flaw was found in the way CUPS handled references in its
file descriptors-handling interface. A remote attacker could, in a
specially-crafted way, query for the list of current print jobs for a
specific printer, leading to a denial of service (cupsd crash).
