Microsoft warned Tuesday of a new, unpatched memory corruption error in its word-processing software, and said that it was investigating reports of "limited" attacks that exploit the problem. The bug can be exploited by adding a string of characters in a Word file that can corrupt the PC's memory and allow the attacker to run unauthorized software on the system, Microsoft wrote in a security advisory. The bug affects many versions of the software, including Word 2000, 2002, and 2003, the Word Viewer 2003 and several versions of Microsoft Works. What else is new another exploited found in a Microsoft product. Now they have to patch this and the recent print spooler 0day DoS vulnerability.
