Once again, a zero-day vulnerability was fixed in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows.
Like every second Tuesday of the month (in America), Microsoft released Patch Tuesday for August 2022 to fix 121 vulnerabilities in its Windows operating systems and related software.
Of the 121 vulnerabilities, 17 were classified as critical, 102 as important, one with a moderate severity level, and finally one with a low severity level.
Specifically, the vulnerabilities are classified as follows:
- 64 are of the EoP (Elevation of Privilege) type;
- 6 allow bypassing of security features;
- 31 are of the RCE (Remote Code Execution) type;
- 12 of type ID (Information Disclosure);
- 7 of the Denial of Service type;
- 1 of spoofing type
- Full details on the cumulative package of updates are available on Microsoft’s official page.
The most serious of the vulnerabilities fixed at the August 2022 patch Tuesday is CVE-2022-34713.
To immediately check for the availability of Microsoft’s August 2022 updates, in Windows 10 simply click on the Start button, then move to the Settings/Update and Security/Windows Update section and select Check for Updates.
In Windows 11, on the other hand, simply click on the Start button, select Settings/Windows Update, click on Check for Updates and proceed, if applicable, to install the patches.
The advice is to back up your system or at least your most important files and folders before applying any of the updates in the newly released cumulative package.
