Summary
This security update resolves vulnerabilities in Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker convinces a user to open a specially crafted document or to go to an untrusted webpage that contains embedded fonts.
To learn more about the vulnerability, see Microsoft Security Bulletin MS15-115.
More Information
Important
- All future security and nonsecurity updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update 2919355 to be installed. We recommend that you install update 2919355 on your Windows RT 8.1-based, Windows 8.1-based, or Windows Server 2012 R2-based computer so that you receive future updates.
- If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.
This security update was rereleased on November 11, 2015, for Windows 7 and Windows Server 2008 R2 to resolve the following issues:
- Resolves crashing that occurred in all supported versions of Microsoft Outlook when users were reading certain emails.
- Resolves crashing that occurred in supported versions of Microsoft PowerPoint when opening PowerPoint Presentations.
- Resolves crashing that occurred in supported versions of Internet Explorer when browsing certain web pages such as groupware web pages in Internet Explorer.
- Resolves problems that occurred while users were logging on to the system. For example, after a user restarted the computer and then pressed Ctrl+Alt+Delete at the logon screen, the screen flashed and then went black. The user was then unable to continue. There may be other, similar logon issues that are related to this issue.
Resolution for customers who are unable to log on to their Windows 7 computers:
If you cannot log on to your Windows 7-based computer because of the known issue mentioned earlier, we recommend that you uninstall security update 3097877 and then install all the latest updates from Windows Update.
The following section provides ways to uninstall the update:
Option 1: Disconnect any digitizer devices
If you have a digitizer device connected to your Windows 7 computer (such as a Wacom device), unplug that device and then continue with logon. After you are logged on, install all the latest updates from Windows Update.
Option 2: Recover the last Restore Point by using System Restore
Access the System Recovery Options. To do this, restart the computer and repeatedly tap the F8 key before the Windows logo appears. If the Windows logo appears, try again. Wait until the Windows logon prompt appears, and then shut down and then restart your computer. You must remove any floppy disks, CDs, and DVDs from your computer before you restart.
Select Repair your Computer.
Select the language, and then log on to the computer.
Note If you do not know the local password, you must start by using a Windows 7 DVD or USB bootable media. Then, access System Recovery Options. For more information about how to obtain Windows 7 DVD or USB bootable media, visit the following Microsoft webpage:
Select System Restore from the menu:
Restore the last restore point. This uninstalls security update 3097877.
Restart the computer into normal mode.
Option 3: Uninstall security update 3097877 at a command prompt
Access the System Recovery Options. To do this, restart the computer and repeatedly tap the F8 key before the Windows logo appears. If the Windows logo appears, try again. Wait until the Windows logon prompt appears, and then shut down and then restart your computer. You must remove any floppy disks, CDs, and DVDs from your computer before you restart.
Select Repair your Computer.
Select the language, and then log on to the computer.
Note If you do not know the local password, you must start by using a Windows 7 DVD or USB bootable media. Then, access System Recovery Options. For more information about how to obtain Windows 7 DVD or USB bootable media, visit the following Microsoft webpage:
Select Command Prompt from the menu:
At the command prompt, run the following command:
dism /image:C:\ /get-packages
Search the results for security update 3097877.
