cupsd in CUPS 1.3.9 and earlier allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. NOTE: this issue can be triggered remotely by leveraging CVE-2008-5184.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
