Microsoft Exchange Server 2016 CU21 | 5.1 Gb The Microsoft development team is pleased to announce the availability of Security Update for Exchange Server 2016 CU21 (KB5004779). This Security Update addresses a remote code execution vulnerability where software cannot properly handle objects in memory.
Exchange Server 2016 CU21 SU1 (Build 15.01.2308.014) - Release date: 7/12/2021
A remote code execution vulnerability exists in Microsoft Exchange software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the System user. An attacker could then install programs; view, change, or delete data; or create new accounts. This cumulative update fixes the issues that are described in the following Microsoft Knowledge Base articles: 4559444 Conversion from HTML to RTF removes non-breaking space in Exchange Server 20164559435 Introduce an OrganizationConfig flag to enable or disable recipient read session in Exchange Server 20164547707 Enable piping for Restore-RecoverableItems in Exchange Server 2019 and 20164559436 Attachments with properties (like Azure Information Protection labels) don't always match in Exchange Server 20164559437 PR_RECIPIENT_ENTRYID is computed if no email address or type in Exchange Server 20164559438 Edge Transport server hangs in Exchange Server 20164559439 EAS creates failure report if a message with unknown recipients is in Drafts in Exchange Server 20164559440 Export to a PST for an eDiscovery search fails in Exchange Server 20164559441 Foreign language characters set in RejectMessageReasonText of a transport rule aren't shown correctly in Exchange Server 20164559442 2080 Events caused by empty values in HKLM\SYSTEM\CurrentControlSet\Services\MSExchange ADAccess\Instance0 in Exchange Server 20164549689 HMA EvoSTS certificate rollover causes authentication prompts due to stalled key on worker process spawn (warmup phase) in Exchange Server 20164559443 Managed Folder Assistant fails with Event ID 9004 NotInBagPropertyErrorException in Exchange Server 20164559446 Changes to Outlook on the web blocked file extensions and MIME types in Exchange Server 2016Exchange Server 2016 includes a number of advanced features for organizations to have a resilient deployment of email across multiple customer sites. It is closely integrated into other products such as Office, SharePoint, Skype for Business (formerly Microsoft Lync) and Office 365, and it shares a similar interface to Exchange Server 2013. Many of the features in Exchange 2016 were first deployed in the cloud with Office 365 before coming to the on-premises version of Exchange. However, some features such as Clutter won't be included because they require Office Graph to work. Exchange 2016 includes improved features and capabilities from previous versions of Exchange. These include a faster database availability group (DAG) failover time, which dropped from about 30 seconds to about 18 seconds, and a 22% lower input/output operations per second (IOPS) from Exchange 2013. Exchange 2016 combines the mailbox and Client Access Server (CAS) roles, which should allow for simpler designs and architecture. It also includes support for BitLocker to provide additional protection for data at rest as well as enhancements to support hybrid Exchange setups. Exchange team veteran Greg Taylor explains how the on-premises version of Exchange 2016 benefits from the proven cloud-based features and functionality of Exchange Online. Microsoft Corporation, leading developer of personal-computer software systems and applications. The company also publishes books and multimedia titles, offers e-mail services, and sells electronic game systems, computer peripherals (input/output devices), and portable media players. It has sales offices throughout the world. Product: Microsoft Exchange Server
