Hot on the heels of the LinkedIn password breach, dating site, eHarmony have reported that "a small fraction" (about 1.5 million) of their user base have also been affected. Like LinkedIn, eHarmony have reset the compromised account's passwords and will send out notification explaining how to reset them. Probably a good time to change your password - check the best practices in the LinkedIn post from earlier today.
LinkedIn have confirmed that a number of user accounts have been compromised. While they have not published the amount of compromised accounts, a Russian forum user uploaded around 6.5 million encrypted user passwords to demonstrate the security breach took place. While the user names have not been included, it's a pretty good bet that they have also been stolen. You can check this site to see if your password was amongst those stolen.
Microsoft have published a Security Bulletin Summary for November 2011. A number of updates have been released including one "critical" and two "important" severity updates.
The patches address remote code execution, elevation of privilege and denial of service vulnerabilities. Importantly, an update has been released to patch the critical vulnerability in the TCP/IP stack (MS11-083). Microsoft report that "the vulnerability could allow remote code execution if an attacker sends a continuous flow of specially crafted UDP packets to a closed port on a target system."
An apparently modified version of the well-publicised Stuxnet worm has been discovered on a number of corporate computer systems in Europe. Analysis suggests that the malware, named Duqu (pronounced dyü-kyü), appears to be based on the Stuxnet source code, giving rise to the possibility that Duqu may have been developed either by the Stuxnet authors or by developers who have had access to the source code.

In response to the volume of malware exploiting Adobe products, Adobe Reader X was released last week with its much anticipated new security feature, Protected Mode.
Protected Mode is based on Microsoft’s "Practical Windows Sandboxing" technique which you can read about here.
What does Protected Mode do? It displays PDF files in a highly restricted and confined environment. The restricted environment will help prevent a booby trapped PDF file from doing anything to your system.
