The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a "DROWN" attack.

The Enhanced Mitigation Experience Toolkit (EMET) benefits enterprises and all computer users by helping to protect against security threats and breaches that can disrupt businesses and daily lives. It does this by anticipating, diverting, terminating, blocking, or otherwise invalidating the most common actions and techniques adversaries might use to compromise a computer.

Introduction Introduction Both Internet Explorer (IE) and Edge have seen significant changes in order to help protect customers from security threats. This work has featured a number of mitigations that together have not only rendered classes of vulnerabilities not-exploitable, but also dramatically raised the cost for attackers to develop a working exploit.

Valve Steam 2.10.91.91 uses weak permissions (Users: read and write) for the Install folder, which allows local users to gain privileges via a Trojan horse steam.exe file.

As we inch closer to the 15th BlueHat Security Conference, we are happy to announce the lineup of speakers and topics for this event. This year will continue with a solid speaker and topic selection that engage engineers, executives, and invited guests to discuss and tackle some of the hardest problems facing the industry today.

Integer underflow in LibreOffice before 4.4.5 and Apache OpenOffice before 4.1.2, when the configuration setting "Load printer settings with the document" is enabled, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via crafted PrinterSetup data in an ODF document.

Hi Folks – Platforms PFE Dan Cuomo here to discuss a common question seen in the field: “My customer is deploying EMET and would like to know if it is supported on Server Operating Systems.” On the surface there is a simple answer to this question, however with a little poking, a little prodding, the question quickly becomes:

Today, I have another exciting expansion of the Microsoft Bounty Programs to announce. Please visit https://aka.ms/bugbounty to find out more. I’ll be discussing this new bounty in my talk at SyScan360 on October 21, 2015. We are delighted to offer a bounty for the .NET Core and ASP.NET Beta which Microsoft released earlier this month.

We are happy to announce the 15th version of the Microsoft BlueHat Security Conference set for January 12-13, 2016. The annual security conference brings internal and external speakers to educate and engage Microsoft’s engineering community and their executives. Work is under way currently to set the schedule for this event. Attendance at BlueHat is open to Microsoft full time employees, contingent staff, and invited researchers, luminaries, partners, and customers.
