Welcome to another edition of patch Tuesday summary blog.  Last month’s patch Tuesday involved patching 21 vulnerabilities over 9 bulletins, while this month we are patching 7 new vulnerabilities over  6 bulletins.

Here is a list of the vulnerabilities fixed in today’s patches:

 

MS12-017 - Vulnerability in DNS Server Could Allow Denial of Service

  • CVE-2012-0006 - DNS Denial of Service Vulnerability

MS12-018 - Vulnerability in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege

  • CVE-2012-0157 - PostMessage Function Vulnerability

MS12-019 - Vulnerability in DirectWrite Could Allow Denial of Service     

  • CVE-2012-0156 - DirectWrite Application Denial of Service Vulnerability

MS12-020 - Vulnerabilities in Remote Desktop Could Allow Remote Code Execution       

  • CVE-2012-0002 - Remote Desktop Protocol Vulnerability
  • CVE-2012-0152 - Terminal Server Denial of Service Vulnerability

MS12-021 - Vulnerability in Visual Studio Could Allow Elevation of Privilege

As shown in the chart above, in March the number of vulnerabilities patched has dropped down. Remember to always be cautious when following links to other sites, as well as opening documents and email attachments, especially when the origin of the documents is unknown.  As we do every month, we’ve released a signature update to address the vulnerabilities fixed in today’s patches.  Happy patching!

Forgive my ignorance, but how does one ensure these threats are covered by their IDP policy?  In our case, we use the *Recommended* template.... woudl that template protect us from the MS12-020 RDP threat, for example?

Hello Skip!

 

  Good question.  Only loading the Recommended template will not give you protection against said RDP attack.  The signature you are looking for called "APP: Remote Desktop Remote Code Execution" is actually found in Recommended-MISC.  My recommendation is to load only this signature and not all of Recommended-MISC.  Skip,  if you have any additional questions regarding this post, please do not hesitate to add additional comments to this thread.

 

Have a great day!

Thanks for the tip!  I do have one more question.....  identifying these threats and creating patches for them is great for the security of your customers' protected networks, to be sure... but finding the time to review each new one and then altering a policy to deal with them is simply not feesible in smaller companies such as mine.. 

For those of us who choose to use a vendor-delivered template, is there one you would recommend that includes things such as the patches listed in these tuesday blogs?  I would have thought 'Recommended' would have included the RDP patch, but clearly I was mistaken. That being the case, is there a more appropriate template to use?  Preferably one that covers the most common and prevelant threats, yet isn't overly consumptive of system resources...?  The IDP_Default template possibly?

Thanks in advance for the advice!

Hi Skip,

 

The default Recommended Policy Template is designed to be a starting point for architecting an IDP policy:

http://kb.juniper.net/InfoCenter/index?page=content&id=KB16489

 

It is broken up by protocol and includes the most commonly used protocols seen in customer networks.

The default template can be copied and additional protocols can be added as needed.

 

Unfortunately, the RDP APP protocol was not listed as one of the common protocols in the default Recommended Policy Template. We are having an internal discussion to update the default Recommended Policy Template to include RDP APP protocol plus other protocols.

 

The IDP_Default Policy Template has all protocols listed, so the RDP APP protocol would have been included, but it has the opposite problem as it includes non-Recommended signatures. Since all protocols and non-Recommended signatures are listed, there is higher chance for false positive or possible performance impact depending on size of IDP and bandwidth going thru it.

 

I would suggest making a copy of the Recommended Policy Template and add Recommended groups on protocols that are known going thru the IDP. So if the RDP APP protocol is being used, add the appropriate [Recommended]APP - <Severity> groups to your copy of the Recommended Policy.

 

The MS12-020 RDP signature is in the [Recommended]APP - Major group and Recommended action is set to drop:

I hope this clarifies,

Alex

Hi Skip,

 

A correction to my orginal comment. Discussing with the signature writers, the MS12-020 RDP Signature is actually in the: [Recommended]MISC - Major group. 

 

Sorry for the confusion.

 

Thanks,

Alex
