DESCRIPTION:
A vulnerability has been discovered in Internet Explorer, which can
be exploited by malicious people to gain knowledge of sensitive
information.

The vulnerability is caused due to a combination of cross-origin
content inclusion being allowed and the manner in which the CSS
parser is fault-tolerant when processing content. This can be
exploited to obtain sensitive information from a web page in another
domain by injecting certain data into the page and then importing it
as a style sheet.

The vulnerability is confirmed in Internet Explorer 6, 7, and 8 on a
fully patched Windows XP SP3. Other versions may also be affected.

SOLUTION:
Do not visit untrusted sites while being logged in to another site.
