New Excel Zero-Day Attack6 February 2007 · Filed in News
There are two interesting things to note (interesting to me, at least):
First, this is an Office vulnerability, not a Windows vulnerability. Therefore, as correctly pointed out in the security advisories, Office 2004 for the Mac is also affected.
Second, although the current attacks are targeted against Excel, this vulnerability extends to all Office documents. This means that other forms of attack could be forthcoming in the near future until the underlying flaw is addressed.
As with some of the other zero-day attacks I’ve discussed here, it looks like the only workaround available at this time is to not open Office documents from untrusted sources. In fact, it would probably be best not to open any unexpected and/or unsolicited Office document from any source, trusted or otherwise.
