Microsoft has announced plans to ship fixes for at least four security holes in the Windows operating system as part of this month's Patch Tuesday batch.
Three of the bulletins carry "remote code execution" risk while the fourth exposes Windows users to denial-of-service attacks.
The updates, which drop around 1:00PM Eastern on November 8, will affect all supported versions of Windows, including the newest Windows 7 and Windows Server 2008 R2.
According to Symantec, the Duqu zero-day vulnerability was exploited via a rigged Word .doc and gave the hackers remote code execution once the file was opened.
Microsoft has not yet issued a security advisory to offer pre-patch mitigation guidance. Microsoft has now issued a security advisory with a temporary fix-it migitation.
