'Description' => %q{
|
||||
This module exploits a stack-based buffer overflow in the handling of the
|
||||
'pFragments' shape property within the Microsoft Word RTF parser. All versions
|
||||
of Microsoft Office 2010, 2007, 2003, and XP prior to the release of the
|
||||
MS10-087 bulletin are vulnerable.
|
||||
|
||||
This module does not attempt to exploit the vulnerability via Microsoft Outlook.
|
||||
|
||||
The Microsoft Word RTF parser was only used by default in versions of Microsoft
|
||||
Word itself prior to Office 2007. With the release of Office 2007, Microsoft
|
||||
began using the Word RTF parser, by default, to handle rich-text messages within
|
||||
Outlook as well. It was possible to configure Outlook 2003 and earlier to use
|
||||
the Microsoft Word engine too, but it was not a default setting.
|
||||
|
||||
It appears as though Microsoft Office 2000 is not vulnerable. It is unlikely that
|
||||
Microsoft will confirm or deny this since Office 2000 has reached its support
|
||||
cycle end-of-life.
