Jan 4 (Reuters) – Some versions of Microsoft
Corp’s (NASDAQ:MSFT) Windows operating system are vulnerable to
attack from hackers exploiting a flaw in the software that
could allow them to remotely take control of a personal
computer.

The software giant warned of the problem on Tuesday in a
special alert. It said it has yet to develop software to plug
the hole in Windows or to figure out a workaround to the
problem.

Microsoft said it is not aware of any attacks that tried to
use the vulnerability, which involves the way Windows renders
graphics on versions of Windows XP, Windows Vista, Windows
Server 2003 and Windows Server 2008.

The problem does not affect Microsoft’s most-recent PC
operating system, Windows 7, and its newest operating system
for servers, Windows Server 2008 R2.
