http://www.microsoft.com/technet/sec.../MS04-022.mspx
Vulnerability in Task Scheduler Could Allow Code Execution (841873)
Issued: July 13, 2004
Version: 1.0

Executive Summary:

This update resolves a newly-discovered, privately reported vulnerability. A
remote code execution vulnerability exists in the Task Scheduler because of
an unchecked buffer. The vulnerability is documented in the Vulnerability
Details section of this bulletin.

If a user is logged on with administrative privileges, an attacker who
successfully exploited this vulnerability could take complete control of an
affected system, including installing programs; viewing, changing, or
deleting data; or creating new accounts with full privileges. However, user
interaction is required to exploit this vulnerability. Users whose accounts
are configured to have fewer privileges on the system would be at less risk
than users who operate with administrative privileges.

We recommend that customers apply the update immediately

Did you ever get this issue resolved? I'm having the same problem since
July, probably when I installed that update. Can't find much info on
Microsoft website or the Net in general. I've seen the resolution to
uninstall, but figured Microsoft would have a least addressed the issue.

I am having problems running my previously scheduled tasks. In
specific, I am not able to create or run tasks based on shortcuts to
an executable. For instance, I had a shutdownauto.lnk shortcut that
contained the line "C:\Windows\System32\shutdown.exe -s". Before this
update, I was able to create a task to run this shortcut every day at
3am. After the update, my task no longer runs.
This is only one of many shortcuts that my organization supports. We
support a large number of computers and rely on tasks to cleanup and
shutdown these pc's at night. Any ideas how I can get this back
without having to uninstall KB841873?
