Description:
Some vulnerabilities have been reported in Internet Explorer, which can be exploited by malicious people to gain knowledge of certain information or potentially compromise a user's system.

1) A memory corruption error within the interpretation of certain DHTML script function calls (e.g. normalize()) to incorrectly created elements can potentially be exploited to execute arbitrary code on a user's system.

2) An unspecified error within the handling of drag and drop operations can be exploited to retrieve content of the TIF folder (Temporary Internet Files) via a specially crafted web page.

3) An unspecified error within the handling of OBJECT tags can be exploited to disclose the path to the TIF folder (Temporary Internet Files) and retrieve its contents via a specially crafted web page.

Solution:
Apply patches.
