A remote code execution vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory, aka 'Microsoft Outlook Remote Code Execution Vulnerability'.

Following the MSRC’s 2020 Most Valuable Security Researchers announced during this year’s Black Hat, we’re excited to announce the top contributing researchers for the 2020 Third Quarter (Q3)! The top three researchers of the 2020 Q3

The Windows Logon installer prior to 4.1.2 did not properly validate file installation paths. This allows an attacker with local user privileges to coerce the installer to write to arbitrary privileged directories. If successful, an attacker can manipulate files used by Windows Logon, cause Denial of Service (DoS) by deleting file(s), or replace system files to potentially achieve elevation of privileges. Note that this can only exploitable during new installations while the installer is running and is not exploitable once installation is finished. Versions 4.1.2 of Windows Logon addresses this issue.

Is it possible to get to a state where memory safety issues would be deterministically mitigated? Our quest to mitigate memory corruption vulnerabilities led us to examine CHERI (Capability Hardware Enhanced RISC Instructions), which provides memory protection features against many exploited vulnerabilities, or in other words, an architectural solution that breaks exploits.

The Azure Sphere Security Research Challenge brought together 70 researchers from 21 countries to help secure Azure Sphere customers and expand Microsoft’s partnerships with the global IoT security research community. During the three-month Azure Sphere Security Research Challenge, researchers surfaced 20 Critical or Important severity security vulnerabilities, with Microsoft awarding $374,300 in bounty awards for 16 bounty eligible reports.

At the Microsoft Security Response Center’s (MSRC), our primary mission is to help protect our customers. One of the ways we do this is by working with security researchers to discover security vulnerabilities in our services and products, and then making sure those that pose a threat to customers get fixed.
