'Name' => 'Publish-It PUI Buffer Overflow (SEH)',
'Description' => %q{
This module exploits a stack based buffer overflow in Publish-It when
processing a specially crafted .PUI file. This vulnerability could be
exploited by a remote attacker to execute arbitrary code on the target
machine by enticing a user of Publish-It to open a malicious .PUI file.
