At Black Hat USA each year, we unveil the Top 100 Security Researcher list to reflect the amazing engagement we get from the community. During this period, we had several thousand researchers engage with the Microsoft Security Response Center (MSRC). We appreciate all the partnership and coordination that goes on throughout the year.

We have tabulated the results from April-June 2018. The Top 5 Bounty Hunters for Q4 are now in. As with our list from Q3, we want to recognize both the leaders in payouts and in number of successful submissions. We appreciate the hard work and dedication of the following individuals and companies who have contributed to securing Microsoft’s products and services over our fourth quarter.

Modern security depends today on collaborative communication of identities and identity data within and across domains. A customer’s digital identity is often the key to accessing services and interacting across the internet. Microsoft has invested heavily in the security and privacy of both our consumer (Microsoft Account) and enterprise (Azure Active Directory) identity solutions.

In Antenna House Office Server Document Converter version V6.1 Pro MR2 for Linux64 (6,1,2018,0312), a crafted Microsoft Word (DOC) document can lead to an out-of-bounds write, resulting in remote code execution. This vulnerability occurs in the `putShapeProperty` method.

In Antenna House Office Server Document Converter version V6.1 Pro MR2 for Linux64 (6,1,2018,0312), a crafted Microsoft Word (DOC) document can lead to an out-of-bounds write, resulting in remote code execution. This vulnerability occurs in the `vbgetfp` method.

An exploitable heap corruption exists in the PowerPoint document conversion functionality of the Antenna House Office Server Document Converter version V6.1 Pro MR2 for Linux64 (6,1,2018,0312). A crafted PowerPoint (PPT) document can lead to heap corruption, resulting in remote code execution.

A vulnerability has been identified in IEC 61850 system configurator (All versions < V5.80), DIGSI 5 (affected as IEC 61850 system configurator is incorporated) (All versions < V7.80), DIGSI 4 (All versions < V4.93), SICAM PAS/PQS (All versions < V8.11), SICAM PQ Analyzer (All versions < V3.11), SICAM SCC (All versions < V9.02 HF3). A service of the affected products listening on all of the host's network interfaces on either port 4884/TCP, 5885/TCP, or port 5886/TCP could allow an attacker to either exfiltrate limited data from the system or to execute code with Microsoft Windows user permissions. Successful exploitation requires an attacker to be able to send a specially crafted network request to the vulnerable service and a user interacting with the service's client application on the host. In order to execute arbitrary code with Microsoft Windows user permissions, an attacker must be able to plant the code in advance on the host by other means. The vulnerability has limited impact...
