January 8, 2019—KB4480968 (Monthly Rollup)

Applies to: Windows Server 2008 Service Pack 2

Improvements and fixes


This security update addresses the following issues:

  • Provides protections against an additional subclass of speculative execution side-channel vulnerability known as Speculative Store Bypass (CVE-2018-3639) for AMD-based computers. These protections aren't enabled by default. For Windows Server guidance, follow the instructions in KB4072698. Use this guidance document to enable mitigations for Speculative Store Bypass (CVE-2018-3639). Additionally, use the mitigations that have already been released for Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754).

  • Addresses an issue that affects PowerShell remoting loop back using non-administrator accounts. For more details, see Windows Security change affecting PowerShell

  • Security updates to Windows Kernel, Windows Storage and Filesystems, Windows Wireless Networking, and the Microsoft JET Database Engine.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

Known issues in this update


Symptom Workaround
Local users who are part of the local “Administrators“ group may not be able to remotely access shares on Windows Server 2008 SP2 machines after installing the January 8th, 2019 security updates. This does not affect domain accounts in the local "Administrators" group.

This issue is resolved in KB4487354.

Applications that use a Microsoft Jet database with the Microsoft Access 97 file format may fail to open if the database has column names greater than 32 characters. The database will fail to open with the error, “Unrecognized Database Format”.

Use one of the following options:

Option 1: Modify the database to ensure that all column names are less than or equal to 32 characters.

Option 2: Convert the database to the .accdb file format. To use the .accdb file format, you must change the Connection string after conversion.

The easiest way to convert is to use Microsoft Access 2010 or earlier.

  1. Use Microsoft Access to open a database that has an older file format.
  2. You will be asked if you would like to convert. Click Yes and save the database with the .accdb extension.

Option 3: Convert the database to a newer .mdb file format. This doesn’t require a change to the Connection string.

  1. Use Microsoft Access to open a database that has an older file format.
  2. You will be asked if you would like to convert. Click Yes and save the database with the .accdb file extension.
  3. Open the .accdb.
  4. From the File menu, click Save as and select Access 2002-2003 Database.
Microsoft is working on a resolution and estimates a solution will be available early February.
