Technical Description:
----------------------
* Cursor and Icon Format Handling Vulnerability - CAN-2004-1049: 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.
* Windows Kernel Vulnerability - CAN-2004-1305: A denial of service
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 cause the operating
system to become unresponsive. The operating system would have to be restarted
to restore functionality.

NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an
Anti-Virus product which automatically notifies the perceived sender of a
message it believes is infected may well cause more harm than good. Someone who
did not actually send you a virus may receive the notification and scramble
their support staff to find an infection which never existed in the first
place. Suggest such notifications be disabled by whomever is responsible for
your AV, or at least that the idea is considered.
