Microsoft's today released 13 bulletins addressing 26 vulnerabilities. 11 bulletins affect Windows and 2 affect older versions of Microsoft Office.
The new patches address issues such as one for Windows that could be exploited to take control of a computer and another one that has resided in the 32-bit Windows kernel since its release 17 years ago.

MS10-013, which addresses a Critical vulnerability in DirectShow. This issue is Critical on all supported versions of Windows except Itanium based server products and has an Exploitability Index rating of 1. To exploit the vulnerability, an attacker could host a malicious AVI file on a website and convince a user to visit the site, or send the file via email and convince the a user to open it.
MS10-006 is also Critical on all versions of Windows, except Windows Vista and Windows Server 2008, and addresses 2 vulnerabilities in SMB Client. One of the vulnerabilities has an Exploitability Index rating of 1. In the simplest scenario, a system connecting to a network file share is an SMB Client. The issue occurs during the client/server negotiation phase of the connection. In order to exploit this issue, an attacker would need to host a malicious server and convince a client system to connect to it. An attacker could also try to perform a man-in-the-middle attack by responding to SMB requests from clients. Microsoft expects attempts to exploit would be more likely to result in a Denial of Service than in Remote Code Execution.
MS10-007 addresses a Critical vulnerability in Windows Shell Handler that affects Windows 2000, Windows XP, and Windows Server 2003. The attack vector is through a specially crafted link that appears to the ShellExecute API to be a valid link. This issue has not been publicly exposed but Microsoft gives it an Exploitability Index rating of 1, urging customers on affected platforms to install it as soon as possible.
MS10-008 is a cumulative update for ActiveX Killbits and is also Critical. A Killbit is not an update that addresses the underlying vulnerability. It is a registry setting that keeps the vulnerable ActiveX control from running in Internet Explorer.
Microsoft also patched a 17 year-old issue related to a vulnerability in Windows kernel that could allow elevation of privilege. Microsoft is aware of publicly available proof-of-concept code for that issue, but is not aware of any active attacks at this time.
Users may already have the updates if they have automatic updating turned on. All those who have automatic updating turned on could go to Microsoft Update. Microsoft Update is an online tool that will scan a computer and provide a report about what updates a computer needs.
