The "Untrusted Scripted Paste" issue involves a vulnerability in Internet
Explorer that could allow a malicious hacker to circumvent certain
Internet Explorer security safeguards. This vulnerability makes it
possible for a malicious Web site operator to read the contents of a file
on the user's computer that is in a known location. This could also be
used to view the contents of a file on a network to which the user has
access, and whose direct path name is known by the attacker. There have
not been any reports of customers being affected by this problem.
This vulnerability could also affect software that uses Hypertext Markup
Language (HTML) functionality provided by Internet Explorer, even if
Internet Explorer is not used as your default browser.
