Microsoft released Security Advisory 2719615 which relates to a Remote Code Execution issue involving MSXML Core Services 3.0, 4.0, 5.0, and 6.0. The vulnerability affects all supported releases of Microsoft Windows, and all supported editions of Microsoft Office 2003 and Microsoft Office 2007.

As described in the Security Advisory:
"The vulnerability could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker would have no way to force users to visit such a website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website."


Microsoft Fix it

As an interim work-around, Microsoft has provided a Microsoft Fix it solution that blocks the attack vector for this vulnerability.

The Fix it solution is available from Microsoft KB Article 2719615, with direct links to the download files to enable and disable the solution below.  I suggest that you save both files so that you can disable the solution prior to installing the update when it is released.

Firefox 13.0.1 was released to address problems encountered after the Adobe Flash Player update caused Firefox to freeze or crash (see Flash Player Update Causes Firefox Crashes).

The Flash Player update included Protected Mode for users of Firefox 4.0 and greater on Windows Vista and higher.  The purpose of Protected Mode is to limit the impact of attacks launched from malicious Flash content (SWF files).

Edit Note:  Also see Adobe Flash Player "Plug-in Version" Updated


What's New


The Release Notes include fixed features in version 13.0.1.
  • FIXED -- Windows Messenger did not load in Hotmail, and the Hotmail inbox did not auto-update (764546, fixed in 13.0.1)
  • FIXED -- Hebrew text sometimes rendered incorrectly (756850, fixed in 13.0.1)
  • FIXED -- Flash 11.3 sometimes caused a crash on quit (747683, fixed in 13.0.1)
  •  

      Update

      The update to Firefox 13.0.1 will be offered through the browser update mechanism after any impacts related to the Microsoft Security Updates are analyzed.  To get the update now, select "Help" from the Firefox menu at the upper left of the browser window, then pick "About Firefox."  Mac users need to select "About Firefox" from the Firefox menu.

      If you do not use the English language version, Fully Localized Versions are available for download.

      Adobe Flash Player "Plug-in Version" Updated

      As indicated by the comments in Mozilla Firefox 13.0.1 Addresses Adobe Flash Crashes, the Firefox update did not solve all of the problems people who use the "Plug-in Version" (non-IE) have been having with Adobe Flash Player since the update to include Protected Mode (“sandboxing”)
      Thanks to ky331 who reported:
      1) Flash Player plug-in version only (for browsers othan than IE) has been updated to 11.3.300.262
      [Flash ActiveX for IE remains at 11.3.300.257 ]

      2) Users of Sandboxie experiencing problems with Flash 11.3 should update Sandboxie to version 3.72
      http://www.sandboxie.com/index.php?VersionChanges#v_3_72

      I recommend the direct download link for the update since it does not include the unnecessary, pre-checked optional McAfee Security Scan Plus scan.  Alternatively, the update is available at the Adobe Flash Player Download Center.
      • Non-IE (Opera, Firefox, Etc.):  http://download.macromedia.com/get/flashplayer/current/licensing/win/install_flash_player_11_plugin.exe
      • Flash Player Uninstaller:  http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe


      Verify Installation

      To verify the Adobe Flash Player version number installed on your computer, go to the About Flash Player page, or right-click on content running in Flash Player and select "About Adobe Flash Player" from the menu.

      Firefox 'New Tab' Feature Exposes Secure Information

      To contact us Click HERE
      Tweet This


      A report at The Register indicates that the "New Tab" thumbnail feature in Firefox 13 is "taking snapshots of the user's HTTPS session content".

      The reader of The Register indicated when he opened a new tab, he was presented with his earlier online banking and webmail sessions, complete with account number information, balance, etc.
       
      On the computer where I generally have 16-20 tabs open, the new tab did indeed include thumbnails of cached pages of sites I had logged on to. On a second computer that generally has only four tabs open, my email page was prominently displayed.

      Although the display of the cached pages is highly undesirable, since my Firefox profile is associated with my computer logon, I can see that the thumbnail is displaying the past page visited and, in some cases, the page currently displayed on another tab! 

      Recommendations

      If you use a shared or public computer use the Private Browsing feature:   
      At the top of the Firefox window, click the Firefox button (Tools menu in Windows XP) and select "Start Private Browsing" (Keyboard shortcut = Ctrl+Shift+P).
       
      Although it will not help for an existing session, use the setting to clear history when Firefox closes.    
      At the top of the Firefox window, click the Firefox button (Tools menu in Windows XP).  Select Options > Privacy > Clear history when Firefox closes.  When you relaunch Firefox and click the "New Tab" button, empty thumbnails with just the site name are presented.

      According to Mozilla, the new tab appears when you click the “+” at the end of your tab strip. Strangely, although I have the latest version installed, some customizations or an installed add-on apparently result in no "+" at the end of the tab strip. For standard installations, apparently there is a small button, in the upper right corner that hides the site tiles, leaving only the small button visible.  Perhaps a Security Garden reader can confirm that and provide a link to a screen capture.


      Mozilla Statement

      Following is the statement provided by Mozilla when presented with the issue by The Register:


      "We are aware of the concern and have a fix that will be released in a future version of Firefox. Mozilla remains resolute in its commitment to privacy and user control. The new tab thumbnail feature within Firefox does not  transmit nor store personal information outside the user's direct control.

      The new tab thumbnails are based on  users' browsing history. All information is contained within the browser and can be deleted at any time. Users can also switch back to using blank new tab screens by clicking the square icon in the top right corner of the browser. That will change the default preference to show a blank page, rather than the most visited websites when a new tab is opened.
      Users who share their computer or use Firefox on a public computer should follow best practices for protecting their privacy by utilizing the built-in privacy tools in in Firefox, such as Private Browsing Mode.

      Microsoft .NET Framework Repair Tool

      Anyone who has every had a problem with .NET Framework, particularly a repeatedly offered security update, knows how difficult it can be to fix. Without a specific error code, it is more difficult to research the source of the problem.

      Until recently, the primary go-to source for help was Aaron Stebner's WebLog on MSDN Blogs at Unified .NET Framework Troubleshooting Guide. I have also provided the recommendation to install .NET Framework security updates, with a shutdown/restart and separately from other security updates.

      Troubleshooting .NET Framework problems may be near an end with the release by Microsoft of the Microsoft .NET Framework Repair Tool. As described in Microsoft KB Article 2698555,

      "The tool may make one or more of several possible changes to the installed product. For example, it may correct the state of Windows Installer on the computer, reset the DACLs on certain folders, or resolve some issues that are related to invalid or corrupted update registration.

      The tool follows a four-step process:
      1. Try to troubleshoot the issue.
      2. Apply the fixes (with user consent).
      3. Try to repair the .NET Framework 4.
      4. Collect logs (with user consent)."
