Microsoft plans to issue seven security bulletins in the January Patch Tuesday release next week, fixing six vulnerabilities rated important and one rated critical. The bugs affect a variety of products, including Windows XP, Vista, Windows 7, Server 2003 and 2008 and Microsoft Developer Tools and Software.

Just three of the seven bulletins Microsoft will issue on Jan. 10 will fix a vulnerability that could lead to remote code execution. The others can either lead to elevation of privilege or information disclosure. However, there is one bulletin that Microsoft has said can also lead to "security feature bypass," something that isn't typically seen on the company's security bulletins.
