"BSOD" was coined by people working with the computers. the real name is called a "STOP" error.
a "Black screen of death" is completely meaningless. One could simply call a computer where one has forgotten to turn the monitor on by that moniker.
But, anyway.
As usual, their technical staff are apparently on vacation.
Prevx was alerted to the problem by users of its security software last week, Morris said. Microsoft apparently made changes to the Access Control List (ACL), a list of permissions for a logged-on user. The ACL interacts with registry keys, creating visible desktop features such as a sidebar.
Access Control Lists are a feature of the NTFS file system and apply to files, not users. each user is identified by a Security Token, or SID. Access Control Lists likely reference specific user SIDs as well as the generic SIDs for such things as the everything group and "backup operators" and so forth.
Registry keys also have Permissions settings as well- this is likely what is being referred to. Although being that the Access Control List is therefore stored in the registry it doesn't really interact with anything. This is one of my pet peeves, "technical" journals saying that data is interacting with anything. That simply doesn't happen; programs interact. Data is simply presented in some way which may or may not be interactive. The Sidebar is created by sidebar.exe, they are instead referring to the ACL of the registry keys that sidebar accesses as having incorrect permissions settings causing sidebar to not function. the data does not create the sidebar. the sidebar uses the data to determine what will be shown IN the sidebar.
Aside from their completely incorrect technical representation of the problem though, I really have nothing to complain about it.
