Excel Bugs Affect Office 2004 for Mac

Microsoft has updated its critical security advisory on Excel, put out on its July 10 Patch Tuesday, to include Office 2004 for Mac.

Microsoft's MS07-036 advisory covers three critical Excel bugs, all remotely exploitable.

This isn't a patch to ignore, security analysts say, given that vulnerable systems can be taken with a Trojan.

"Vulnerabilities in Office applications have been a favorite attack method among cybercrooks," Dave Marcus, security research and communications manager at McAfee Avert Labs, said in a statement on Patch Tuesday. "Trojan horse attacks often use rigged Office files that exploit vulnerabilities in the productivity applications."
