What causes the vulnerability?
An unchecked buffer in the TCP/IP Protocol driver.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.
Workarounds
Block IP packets containing IP source route options 131 and 137 at the firewall
Disable IP Source Routing
What does the update do?
The update removes the vulnerability by modifying the way that TCP/IP Protocol driver validates the length of a message before it passes the message to the allocated buffer.

I'm really fed up with this sort of hole in Windows, you just can't claim reliability or security if you don't validate input length on a system where continuing past the end of the buffer could mean parts of the program get overwritten by the data stream. In effect you are allowing an atacker to insert their own sub-routines into the program.
IMHO The most basic check is - If I have assigned N bytes storage to accept data, then I should stop accepting data when I get to N bytes. :mad: :mad: :mad: /RANT

There are several ways of keeping Microsoft Systems Patched - these seem to be complementary. If you do not have broad band check the sizes of the downloads - most of the small ones are essential ! Whereas the larger ones may be for things like .NET that you don't use..

A - Windows update - ciritical patches for Windows and IE
If you have Windows 98 / 2K / XP / 2003 your first stop should be http://windowsupdate.microsoft.com - download patches for windows and IE

B - MSBA Checks more patches and some security settings http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/tools/mbsahome.asp
The Microsoft Baseline Security Analyzer will check for patches AND will also look at file shares and simple serurity settings.

NOTE: MBSA and Windows Update (WU) analyze systems in different ways. WU for instance only carries critical updates for the Windows operating system, whereas MBSA (through HFNetChk) will report missing security updates for the Windows operating system and other Microsoft products such as SQL Server.

C - Search the list of patches by Application name http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/current.asp
Microsoft's HotFix & Security Bulletin List This lists all the main security patches (right back to 1998) - you can also search by product - this includes Office / Word and windows 95 & NT4

D - Securty tools http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/tools/tools.asp More specific tools for lockdown of IIS etc. and checking settings on other applications.

Capt'n Midnight

Note: in most of the above links change use EU instead of WWW to stay on this side of the Atlantic
Eg: http://eu.microsoft.com/technet/treeview/default.asp?url=/technet/security/current.asp - Lists current security patches - updated at least once per month.

Microsoft reveals a score of weaknesses
Wednesday, April 14 2004
by Matthew Clark

Software giant Microsoft has admitted to no less than 20 new flaws in its software, the most ever announced at once.

In four separate patches, three of which were deemed "critical," Microsoft demonstrated 20 new weaknesses, including faults that could open a computer up to Blaster-style bugs or could allow a malicious attacker to take control of a victim's PC. Microsoft issues new patches on a monthly basis, but never before has the company issued patches for so many "critical" vulnerabilities all at once.

Indeed, within the three critical patches issued by the firm, the company described eight "critical" vulnerabilities. Prior to Tuesday, Microsoft had issued patches for a mere 10 vulnerabilities during 2004, and just four of those were deemed critical.

Beware unplanned SP2 downloads on April 12

On Tuesday, April 12, Microsoft will turn off the blocking feature that has made it possible for some enterprises to block Windows XP Service Pack 2 downloads by employees who use Automatic Update. That means in companies that used the blocking tool, SP2 will be downloaded automatically to desktop computers that use Windows' Automatic Update feature.

In its April 4 report on business adoption of Windows XP SP2, AssetMetrix warned that a surge of SP2 downloads on April 12 could stress IT help desks and cause "productivity brownouts" among employees. But a Microsoft spokesman downplayed that scenario, saying fewer than 1% of Microsoft's enterprise customers ever used the blocking tool anyway. Small businesses and consumers will be unaffected by the change, he says, because the blocking tool was not available to them.

AssetMetrix advises companies that did use the blocking tool, yet now want employees to upgrade to SP2, to do so gradually before April 12 in order to avoid a big-bang support problem. It's worth noting that April 12, as the second Tuesday of the month, is the same day that Microsoft is scheduled to release its monthly software patches, if any are forthcoming.

A vulnerability exists in [Windows/IE/Word] that could allow an attacker who successfully exploited this vulnerable to take complete control of the affected system.

So critical patches for all currently supported versions of Windows even if previously patched to date ( 98 to 64 Bit ) and IE and Word 2000/2002

http://www.microsoft.com/technet/security/current.aspx - Bump.

You can now use Microsoft Update which updates Windows and Office in the one go, makes life a lot easier.

Also, dont trust the Windows Firewall jt only stops inbound connections leaving you vunerable to a host of trojans that can still "phone home".

And of course keep your antivirus/spyware/adware apps updated as well.

http://secunia.com/advisories/18255/

The vulnerability is caused due to an error in the handling of Windows Metafile files (".wmf")... Such records allow arbitrary user-defined function to be executed when the rendering of a WMF file fails. This can be exploited to execute arbitrary code by tricking a user into opening a malicious ".wmf" file in "Windows Picture and Fax Viewer" or previewing a malicious ".wmf" file in explorer (i.e. opening a folder containing a malicious image file).

The vulnerability can also be exploited automatically when a user visits a malicious web site using Microsoft Internet Explorer.

NOTE: Exploit code is publicly available. This is being exploited in the wild. The vulnerability can also be triggered from explorer if the malicious file has been saved to a folder and renamed to other image file extensions like ".jpg", ".gif, ".tif", and ".png" etc.

"F-Secure reports detecting 57 different malicious WMF files in the wild so far."

If your concerned for you security on the web please follow these steps until Microsoft releases a patch for it. This will unregister, or "disable" for want of a better word, the file that is causing this exploit.

1. Click on the Start button on the taskbar.
2. Click on Run...
3. Type "regsvr32 /u shimgvw.dll" to disable.
4. Click ok when the change dialog appears.

The recent WMF patch protects IE from dodgy images, this one is to protect IE from dodgy text. Also there is some speculation that the WMF hole in GDI.exe could have been present as far back as Windows 3.0 so you can't assume IE will ever be safe even if it goes 6 months without needing a patch.

Alternatives to IE
http://www.opera.com - Best out of the box browser, closed source but so far the most secure windows browser.
http://www.mozilla.com - most tweakable browser, open source, generally needs patching more often than opera

On Microsoft Windows 2000, Windows XP, and Windows Server 2003 systems, an attacker could exploit this vulnerability without authentication to run arbitrary code. It is possible that this vulnerability could be used in the crafting of a wormable exploit.

http://www.theregister.co.uk/2011/06/10/ms_patch_tuesday_june_pre_alert/

Nine of the bulletins earn the dread rating of critical, while the other seven grapple with flaws rated as important. All supported versions of Windows will need patching on 14 June along with various server-side software packages and applications, including the .NET framework and SQL Server. Internet Explorer, which is affected by two bulletins, will also need some fiddling under the bonnet.

Office suites also need to be updated thanks to a security fix for Excel that also affects the Mac OS X version of the product as well as virtually all versions of the spreadsheet software on Windows, including the most recent 2010 and 2011 editions of the software.

Patches for IE6 through IE10 and Office , usual Remote Code Execution stuff

The first patches say there might be less damage if you aren't logged in with admin rights, which is then undermined because the last patch is about attackers gaining elevated privileges anyway.
