Upozornění

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.

SharePoint Server 2019

This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see the following security advisories:

This security update contains improvements and fixes for the following nonsecurity issues:

  • Fixes an issue in which the arrowhead symbol that signifies an additional fly-out shortcut menu disappears or appears incorrectly on the Advanced option on a task callout that’s found in a SharePoint task list.
  • Fixes an issue in which site creation fails if only Security Assertion Markup Language (SAML)-based authentication is enabled.
  • Fixes an issue that prevents images from appearing in modern News posts and Pages if the site collection is using the Turkish language.
  • Fixes an issue in which the Copy To function doesn’t work for folders that contain .vol files larger than 4 GB in size.
  • Fixes the issue that causes list totals to be misaligned while displaying sum total.
  • To improve accessibility, fixes the following issues:
  • Always use „all documents“ as aria-label for the first view on the View Selector menu.
  • View Selector items specify a non-existent „view“ role and aren’t correctly recognized by screen readers.
This update also fixes the following issues. To fix these completely, you must also install KB 4484331 together with this update:

  • Fixes an accessibility issue in which focus is trapped in the Close button in the Share dialog box when you navigate through screen readers.
  • Fixes an issue where anonymous users are unexpectedly prompted for credentials while using the modern experience in SharePoint sites that allow anonymous access. This includes modern Team sites and Communication sites.
  • Fixes an issue where the screen readers are unable to detect the people field or required flag of modern pages.
  • Fixes an issue where screen readers cannot read the required flag in the modern document library folder creation experience.
  • Fixes an issue that affects choice fields in the modern list experience. After a value is set for a choice field, users cannot overwrite that value by using a blank value, even if the field doesn’t require a value.
  • Fixes an issue that occurs when you navigate between modern pages through in-app transition. If the URL contained the „?#“ character sequence, the „?“ is removed from the navigated page URL. This can affect how web frameworks render the page.
