In my blog post WinRAR Code Execution Vulnerability CVE-2023-40477 I had mentioned a vulnerability in WinRAR, which has been fixed with the update to WinRAR version 6.23. Andreas Marx from AV-Test recently pointed out that basically all software that uses WinRAR libraries is vulnerable in principle and needs to be updated to newer versions. I had added the information to the above blog post and pointed out that virus scanners and security software may use these outdated WinRAR libraries. So if necessary check the Windows system for the library files mentioned in the blog post. Addendum: According to the WinRAR developer the libraries are not affected by the vulnerability.

[German]Microsoft has updated the Edge browser to version 116.0.1938.62 as of August 25, 2023. It is a maintenance update that probably fixes an issue with ignored group policies when logging in to the user account and also fixes vulnerabilities.
[German]Since weeks, administrators have been complaining about problems with remote desktop connections that can occur on Windows 11 22H2.

[German]The old recommendation not to install a month's preview updates immediatly has proven itself again in August 2023. The optional preview updates released on August 22, 2023 are supposed to fix numerous bugs and provide new group policies in Windows 11 for the update installation. But Microsoft had to admit that the updates cause an UNSUPPORTED_PROCESSOR BlueScreen on some machines. The updates were therefore withdrawn for some machines.
