Date: 31 Jul 2005 02:25:40 -0000 To: vuln-dev@securityfocus.com('binary' encoding is not supported, stored as-is) font book allows users to add new "collections" of fonts with a name of thier choice. When the name of the collection is a very very very large string of characters it crashes. here is the gdb output:

for this to crash the collection name must contain thousands of characters.
