CVE-2009-1196
First published: Wed Apr 22 2009(Updated: )
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). Acknowledgements: Red Hat would like to thank Swen van Brussel for reporting this issue.
