On Tuesday, Microsoft’s flubbed patch

On May 10, the company released security updates to fix 75 vulnerabilities, eight of which were classified as serious and three that were being exploited by attackers. The issues fixed in Patch Tuesday in May were significant, but soon there were issues for some Microsoft users, who reported authentication errors after installing the latest updates. It affected people who used Windows client and server platforms and systems running all versions of Windows, including Windows 11 and Windows Server 2022.

In an attempt to fix the issue, the company was forced to release an out-of-band update for Windows 10, Windows 11, and Windows Server 2008, 2012, 2016, 2019, and 2022 on May 20th. The update will not be automatically installed – you must download it from the Microsoft Update Catalog.

Mozilla fixed issues in another update, Firefox 100.0.2, Firefox ESR 91.9.1, Firefox for Android 100.3, and Thunderbird 91.9.1. Click these update buttons.


May’s Android security update is very important, as it fixes 36 vulnerabilities, including one that is already being exploited by attackers. The already exploited flaw is a privilege escalation error in the Linux kernel known as “The Dirty Pipe”.

The flaw, which affects newer Android devices with Android 12 and later, was revealed by Google in February, but it took a while to reach the devices.
