Another security flaw discovered in Microsoft Excel

By Justin Mann on
Office users beware, another vulnerability has been discovered in Microsoft Excel. Affecting many versions of Excel, including 2000, 2002 and 2003, the flaw stems from a problem in the way Excel handles repairing a document containing long styles. It could result in memory corruption, which could ultimately lead to arbitrary code execution. Like the majority of Office flaws, it requires some user intervention:

"In order for this attack to be carried out, a user must first open a malicious Excel document that is sent as an e-mail attachment or otherwise provided to them by an attacker," the spokesman said in an e-mail. "Opening the Excel document out of e-mail will prompt the user to be careful about opening the attachment."
While the flaw could result in system damage, a careful user shouldn't have to worry. In office settings in which documents are routinely emailed, however, extra precaution is advised. No word yet from Microsoft about when a patch can be expected.
