SharePoint Server 2019 CU – Odkaz ke stažení CU:

Po dokončení instalace nezapomeňte na spuštění průvodce konfigurací služby SharePoint 2019 (SharePoint 2019 Products Configuration Wizard), nebo příkazu:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install


Vždy instalujte oba balíčky a to v pořadí:

  1. language independent (aktualizuje jazykové nezávislé komponenty)
  2. language dependent (aktualizuje jazykové závislé komponenty)

V případě jazykově závislých balíčku (language dependent) nezáleží jaký jazyk si ve výsledku vyberete, jelikož každý balíček obsahuje aktualizace pro všechny jazyky.

V případě, že na SharePoint Server 2019 farmu instalujete nový jazykový balíček, je nutné následně znova nainstalovat jazykové závislý balíček (language dependent).

Nezapomínejte, že krom SharePoint je nutné mít aktualizovanou i službu Distributed Cache, viz. Jak správně aktualizovat Distributed Cache a v případě Office Online Serveru musíte mít aktuální RTM verzi, viz.  Jak aktualizovat Office Online Server.

Obsažené opravy a vylepšení

Seznam oprav a vylepšení tohoto CU je soubor výňatků z oficiálních Microsoft KB článků v původním jazyce (EN).

SharePoint Server 2019

This security update resolves a cross-site-scripting (XSS) vulnerability that exists if Microsoft SharePoint Server does not correctly sanitize a specially crafted web request to an affected SharePoint server. To learn more about the vulnerability, see the following security advisories:

This security update contains improvements and fixes for the following nonsecurity issues in SharePoint Server 2019:

  • Users navigate to a document library and open a Links list in Job Access With Speech (JAWS) by using a keyboard shortcut (Alt+F7) to see all links on the page. Every document in the library contains the Open Menu link to open the Edit Control Block (ECB) menu. Therefore, it is not possible to know which document belongs to which link. This update fixes the issue.

    Note To fix this issue, you have to install update 4484277 together with this update.

  • Fixes an issue that prevents users from switching content type when they create items in a list.
  • Removes the Link command from the New menu in custom lists when content types are enabled.

Note To fix these issues, you have to install update 4484277 together with this update.

  • When you have a hyperlink column as the first column in your view, and you have a very long navigation list, the edit box for the hyperlink column in Quick Edit opens underneath the navigation pane. This makes it difficult to edit or add a value in the edit box.
  • Fixes an issue in which creating a site master fails if multiple authentication methods are used for the web application.
  • When you use the Edge browser, CSPReporting.aspx is requested multiple times during page loading when you access modern pages. This update fixes this issue.
  • Screen readers such as Narrator don’t show an „alt“ text entry for icons of Search buttons when you bulk edit multiple resources.
  • After you import an updated thesaurus into the Search Service Application, you may see a „something went wrong“ error message when you search from the „Search Box“.
  • When you use the Finnish locale version, the dates for Blog and List items don’t render correctly. This update fixes this issue.
  • When you copy items that are declared as records through Windows Explorer, the copied items keep the record declaration status. This update fixes this issue.
  • Fixes an issue that causes content deployment jobs to fail if a document library contains a file that has multiple versions.

This security update contains fixes for the following nonsecurity issues in Project Server 2019:

  • After you edit a project in Project Web App, it may take a long time to save the project. This is especially true if there are many custom field values. This causes slower publishing, check-in jobs, and other related actions.
  • Editing a project in Project Web App or approving status updates uses the Project Calculation Service (PCS). In some situations, PCS crashes while it closes the given project. The crash detail is logged in the Unified Logging System (ULS) logs, and it resembles the following:

    „The worker encountered a very serious error and will shut down. Exception code was: 0xc0000005 (EXCEPTION_ACCESS_VIOLATION).“

  • Consider the following scenario:
    • You have an enterprise resource custom field.
    • You edit a resource and assign a value to the field.
    • You delete the enterprise resource field.
    • You edit the resource, and save your changes.

In this scenario, the process fails, and you receive the following error message:

„Unknown error has occurred“

Office Online Server

This security update resolves a remote code execution vulnerability that exists in Microsoft Word software if the program does not correctly handle objects in memory. To learn more about the vulnerability, see the following:

Known issues in this update

After you install this security update, Office Online Server logging will be set to Verbose by default. We recommend that you change this setting to Medium by running the following command:

Set-OfficeWebAppsFarm -LogVerbosity “Medium”

Note After you run the command, you have to restart the Office Online Service. To do this, run the following command:

Restart-Service WACSM
