-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Word. User interaction is required
to exploit this vulnerability in that the target must visit a malicious
page or open a malicious file.

The specific flaw exists within the code responsible for parsing the
plcffldMom structure within .doc files. By crafting malicious values
within this structure an attacker can force the program to make faulty
heap memory allocations. This can be leveraged to execute remote code
under the context of the user running the application.
