Last week, we released Security Advisory 2607712, notifying customers that fraudulent digital certificates had been issued by certificate authority DigiNotar. We’d like to follow up on that notification in this blog post by explaining more about the potential risks and actions you can take to protect yourself from any potential attacks that would leverage those fraudulent certificates.

Vulnerabilities in DNS Server Could Allow Remote Code Execution

Tuesday, August 09, 2011

Today we released MS11-058 to address two vulnerabilities in the Microsoft DNS Service. One of the two issues, CVE-2011-1966, could potentially allow an attacker who successfully exploited the vulnerability to run arbitrary code on Windows Server 2008 and Windows Server 2008 R2 DNS servers having a particular DNS configuration. We’d like to share more detail in this blog post and help you make a risk decision for your environment.

A guide to exploit mitigations and the July 2011 security bulletin release

Tuesday, July 12, 2011

Hello all – Over the years we’ve often talked about exploit mitigations – DEP, ASLR, SEHOP and so forth – as effective tools for improving computer security, reducing risk, preventing attacks, and minimizing operational disruption. Today we’re releasing a user’s guide to the toolbox: “Mitigating Software Vulnerabilities,” a white paper with practical information on choosing and enabling those mitigations.

Mitigating Software Vulnerabilities

Tuesday, July 12, 2011

How can you protect yourself, your business, and your customers when faced with an unknown or unpatched software vulnerability? This question can be difficult to answer but it is nevertheless worthy of thoughtful consideration. One particularly noteworthy answer to this question is provided in the form of exploit mitigation technologies such as DEP and ASLR, which are designed to make it difficult and costly for an attacker to exploit a software vulnerability.
