Microsoft Plugs Three Windows Security Holes
Summary: Microsoft released security updates to fix at least three vulnerabilities in its Windows operating systems, including one rated critical that affects all versions of Windows and could be exploited by getting users to visit a malicious or compromised website. The patches did not address five zero-day flaws for which exploit code is publicly available, and Microsoft instead released two FixIt tools as stopgap mitigations.
Key Takeaway: Five known vulnerabilities with publicly available exploit code remained unpatched at release, leaving Windows users - particularly Internet Explorer users - dependent on manual stopgap fixes rather than an official patch.
