In today’s SensCy Cyber Brief, your SensCy team is reviewing Microsoft’s latest series of patches. Today’s Patch Tuesday comes with fixes for an actively exploited zero-day vulnerability, one non-exploited zero-day vulnerability, and a total of 121 flaws.
What is Patch Tuesday?
Patch Tuesday is Microsoft’s initiative to release new security fixes for the Windows operating system and any other Microsoft software on a Monthly basis. Your SensCy team will monitor such releases and provide you with our observations and recommendations.
Why is it important?
This month’s patch Tuesday is particularly important because it fixes Zero-day Vulnerabilities (a vulnerability in a system or device that has been disclosed but not previously patched). The SensCy team urges Microsoft users to immediately install these patches.
One of the zero-day vulnerabilities was actively exploited by a hacker and is called “DogWalk.” It was discovered by security researcher Imre Rad in January 2020 but Microsoft decided to wait to release a fix because it wasn’t yet a security issue. Now Microsoft has added a fix for this zero-day on their August Patch Tuesday.
In addition to the zero-day fix, Microsoft is also fixing 121 vulnerabilities, with seventeen classified as “Critical” as they allow remote code executions or elevation of privilege.
Here is a breakdown of each vulnerability category
- 64 Elevation of Privilege Vulnerabilities
- 6 Security Feature Bypass Vulnerabilities
- 31 Remote Code Execution Vulnerabilities
- 12 Information Disclosure Vulnerabilities
- 7 Denial of Service Vulnerabilities
- 1 Spoofing Vulnerability
