[German]On October 14, 2025 (the second Tuesday of the month, Microsoft Patch Day), Microsoft released several security updates for Microsoft Office 2016, as well as the C2R variants (Office 2016-2021 and 365) and other products. This month, serious vulnerabilities in Office were closed. Below is an overview of the available updates.
An overview of the updates can be found on this website (and here for this month). Details are documented in the linked KB articles. The updates are available for the installable MSI version of Microsoft Office (the Click-to-Run packages obtain the updates through other channels).
Microsoft Office 2019/2021/2024 does not appear in the list because it is distributed via Click-to-Run packages and receives security updates via the Office Update feature.
Microsoft Office 2016 and Microsoft Office 2019 are receiving security updates for the last time and are now no longer supported. The 0patch solution will help here in the future (see 0patch secures Microsoft Office 2016 and 2019 after October 2025).
