Microsoft has wrapped up 2010 with a real bang as far as the volume of security vulnerabilities goes.

The company released no less than 17 security bulletins in December 2010, patching no less than 40 vulnerabilities.

However, just a couple of the patch packages are rated Critical, which means that the security holes they’re designed to plug can allow attackers to execute code remotely on a vulnerable computer and gain control over the machine.

The updates resolve security flaws in a range of products, including Office, Windows, Internet Explorer, SharePoint Server and Exchange.

Jerry Bryant, group manager, response communications, Microsoft was kind enough to provide a complete list with all the security bulletins issued by the software giant this month, which customers will be able to find below.

With just two bulletins rated Critical, 14 have been labeled Important and the remaining one is just Moderate.

Customers are of course advised to deploy the updates as soon as possible, with the Redmond giant highlighting two security bulletins as priorities.

“Microsoft recommends that systems administrators prioritize the following Critical bulletins: MS10-090 addressing vulnerabilities in Internet Explorer; and MS10-091 addressing vulnerabilities in Windows,” Bryant explained.

It’s critical to note that Microsoft issued patches for a zero-day vulnerability affecting Internet Explorer (but not IE9 Beta) and also for a flaw which has been exploited by the Stuxnet malware.

The company warned of attacks detected in the wild and designed to leverage both Critical vulnerabilities in order to infect computers with malicious code.
