This security update resolves a Microsoft SharePoint Server spoofing vulnerability. To learn more about the vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2024-26251.
Notes:
This security update contains an improvement and fixes for the following nonsecurity issues in SharePoint Server 2019:
Fixes an issue in which duplicate configuration elements are added to SharePoint Web.config files every time that you run SharePoint upgrade. This activity eventually causes those files to exceed the Web.config file size limitation that’s configured in IIS. This issue generates multiple “HTTP 500.19 - Cannot read configuration file because it exceeds the maximum file size” error messages when you browse a SharePoint website. This fix removes the existing duplicate configuration elements and prevents future duplicates from being added.
Fixes an unexpected exception in the aggregated newsfeed feature.
Improves the reliability of Antimalware Scan Interface (AMSI) integration.
This security update also contains a fix for the following nonsecurity issue. To fix this issue completely, you have to install KB 5002538 together with this update.
Fixes an issue in which you cannot open PDF attachments from list items.
