This vulnerability specifically exists in the handling of a specific control word in an RTF document. Under certain circumstances, Word will copy its property strings into a stack buffer without checking the length, which causes a stack buffer overflow.
Exploitation allows remote attackers to execute arbitrary code on the affected host under the context of the user who opened the malicious RTF document with Microsoft Word.
Exploitation might require that the user open a specially crafted RTF document with a vulnerable application. The most likely exploitation vector involves convincing a user to open an RTF document sent to the user via e-mail or linked on a website.
Since Outlook 2007 uses the Word engine to process e-mails, it is also affected by this vulnerability. The attacker can send the user a specially crafted RTF e-mail. When this e-mail is opened or displayed in the preview pane using Outlook 2007, the vulnerability will be triggered.
Patch Availability:
Microsoft has issued an update to correct this vulnerability at:
http://www.microsoft.com/technet/security/bulletin/MS10-087.mspx
Workaround:
Microsoft recommends reading e-mail in plain-text format as a workaround.
