XMLHTTP Control Can Allow Access to Local Files.

A flaw exists in how the XMLHTTP control applies IE security zone
settings to a redirected data stream returned in response to a
request for data from a web site. A vulnerability results because
an attacker could seek to exploit this flaw and specify a data
source that is on the user's local system. The attacker could
then use this to return information from the local system to the
attacker's web site. 

Impact of vulnerability: Attacker can read files on client system.

Microsoft XML Core Services versions 2.6, 3.0, and 4.0.
An affected version of Microsoft XML Core Services also
ships as part of the following products: 

Microsoft Windows XP 
Microsoft Internet Explorer 6.0 
Microsoft SQL Server 2000 

(note: versions earlier than 2.6 are not affected
files affected include msxml[2-4].dll and are found
in the system32 directory. This might be false
positive if you have earlier version)
