Red Hat Product Errata RHSA-2009:1083 0 normal SHIPPED_LIVE Important: cups security update 2009-06-03 15:50:54 UTC

Description Jan Lieskovsky 2009-04-22 13:48:53 UTC 
Swen van Brussel reported pointer use-after-delete flaw, present in the CUPS directory services routine, processing new data about available printers and printer classes. A remote attacker could suspend, and after a carefully-chosen time interval renew sending of CUPS browse packets to the victim machine
with running cupsd daemon, leading to a denial of service (cupsd daemon
stop or crash).
