- * ---------------------------------------------------------------------
- * Description:
- * A remote code execution vulnerability exists in the way that

- * could try to exploit the vulnerability by constructing a malicious
- * cursor or icon file that could potentially allow remote code
- * execution if a user visited a malicious Web site or viewed a
- * malicious e-mail message. An attacker who successfully exploited
- * this vulnerability could take complete control of an affected
- * system.
