Description Jan Lieskovsky 2009-04-22 09:48:53 EDT
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).


Red Hat would like to thank Swen van Brussel for reporting this issue.
