Hackers are exploiting a vulnerability in Microsoft Word to plant malware on Windows PCs, Microsoft said Tuesday.
The bug in Microsoft Word 2002, 2003, 2007 and 2010 was patched Nov. 9 as part of Microsoft's monthly security update.
Word 2008 and 2011 for the Mac have also been patched, but Microsoft has not yet issued a fix for the same flaw in the older Word 2004. The circulating attacks affect only Windows versions of the suite, however.
