Windows 10: Uninstall KB4552925 probably causes 'semafoor timeout'?

128383nbrfiu · Jun 25, 2020

Hi,

I'm using u VPN to an, ancient, SBS2003. All worked well but as of today I can normally connect but can't access a share. After minutes I get an 'semafoor timeout' language Dutch. I'm the only one with the problem, others can connect normally. Other protocols http, exchange, VNC are working over the VPN. I also can access a share on my local network to a Synology NAS.

Yesterday I installed a few updates: Among others KB4559309 en KB4552925. And perhaps some device drivers but can't find out which: not showing in the history. Because the problem only started today I think/hope that probably one of the updates is the problem and want to uninstall them but without luck. I tried:

- to go back tot a restore point a few days ago but both updates still remain in the history and problem exists.
- Under 'delete update' translation from Dutch I only found 3 updates: 2 from 2017 and 1 from 17 june also the day I updates to 2004

- Tried also safe boot and remove the latest quality updates but the updates are still in the history.

A search for 'semafoor timeout' lead me to outdates network drivers. I tried the WiFi en ethernet on my laptop as well as an ethernet port on a Kenginston-dock. Same problem with all three.

I'm using Windows 10 Home 10.019041 Build 19041

Hope someone has a sollution!

Martin.

:)

Can't find any uninstall options in add/remove programs and intel chipset inst listed in driver cleaner.

Any suggestions? *Confused

KB4552925 Cumulative Update .NET Framework 3.5, 4.8 Windows 10 May 12

May 12, 2020 - KB4552925 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004

Summary

A remote code execution vulnerability exists in .NET Framework software when the software fails to check the source markup of a file. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of .NET Framework. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. The security update addresses the vulnerability by correcting how .NET Framework checks the source markup of a file.

To learn more about the vulnerabilities, go to the following Common Vulnerabilities and Exposures (CVE).

CVE-2020-0605

A denial of service vulnerability exists when .NET Framework improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Framework web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework application. The update addresses the vulnerability by correcting how the .NET Framework web application handles web requests.
