DESCRIPTION:
Four vulnerabilities have been reported in Internet Explorer, which
can be exploited by malicious people to compromise a user's system.

1) An error in the layout handling when accessing an improperly
initialised or deleted object can be exploited to corrupt memory.

2) A use-after-free error when asynchronously accessing NULL objects
can be exploited to dereference an already deleted object.

3) An error may cause a corrupted virtual function table that has
already been deleted to be accessed.

4) An integer overflow error in the JavaScript parsing when
calculating the size of an object in memory during a copy operation
can be exploited to corrupt memory.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

SOLUTION:
Apply patches.
