Another hole found in PowerPoint

Proof-of-concept exploit shows further bug in slideshow software

Microsoft has issued an alert over a new potential zero-day exploit in its PowerPoint presentation software. The exploit is only a proof of concept and is as yet not thought to be in use by attackers.

The new bug comes just days after the monthly Patch Tuesday updates, one of which covered a previous hole in PowerPoint. It is believed to affect only the Office 2003 version of PowerPoint, and may result in remote code execution.

Microsoft released news of the vulnerability on its security blog. Alerts have also been issued by US-CERT and by Secunia, which has rated the problem as 'highly critical'.
