Palm OS Treo smartphones are equipped with a system password lock to secure contents of handheld data from unauthorized access. When this lock is engaged, Treo’s built-in Find feature is still accessible and can be used to perform searches on text in Treo applications and databases (e.g. SMS Messages, Memos, Calendar, Tasks, etc) Search results are accessible, and depending on their size, may be truncated. An attacker may use this vulnerability to view data that was cut or copied from applications prior to the device being locked.”]
