Beware Unexpected PowerPoint Files
If it’s not one thing, it’s another. This time it’s Powerpoint that has a security problem. The details can be read at eWeek. There’s no workaround at the moment.
Microsoft on July 17 released a security advisory with a terse message: Do not open or save unexpected Microsoft Office files, even if they come unexpectedly from a trusted source.
The company’s advisory comes less than a week after virus hunters discovered that a previously undocumented flaw in Microsoft PowerPoint was being exploited to plant a keystroke logger on infected Windows systems.
Microsoft also says
In order for this attack to be carried out, a user must first open a malicious PowerPoint document attached to an e-mail or otherwise provided to them by an attacker.
At this point the best advice is not to open any Microsoft Office file that arrives unexpectedly, even if from a trusted source. Check it out with the sender first.
