Microsoft Fixes 23 Security Flaws

---

Microsoft Corp. today released free software updates to fix nearly two dozen security holes in its Windows operating system and Microsoft Office products. At least 17 of the 23 flaws could be exploited by attackers to hijack vulnerable systems or to install malicious code, the company warned.

Dig through the details of the advisories and you will see that instructions showing would-be attackers how to exploit at least nine of the flaws have already been posted online. Microsoft also said it has seen at least three of the flaws being actively exploited in the wild. As usual, updates are available via Microsoft Update (Internet Explorer required) or through automatic updates.
