Included in this Patch Tuesday is a Forefront update KB2508823[1] (Client Version: 1.5.1996.0).


We have received a number of reports that the KB2508823 update fails during the install. Once the update fails, the existing Forefront client is also removed. This leaves the machine without any anti-malware protection.

We recommend you hold off deploying the update until confirmation from Microsoft.

Microsoft have posted a similar warning here:

Some readers from Montreal, Canada wrote in about a problem with AVG Anti-Virus 2011 Free Edition 10.0.1024.  The issue is with the all PDF's being quarantined and marked as infected by Luhe.Exploit.PDF.B.

 
It has been reported and noted on the above AVG Forum that an affected version is the following:
 
    AVG Anti-virus 2011 Free Edition 10.0.1204, virus database version 1497/3490 

 
The following url is a conversation on the issue:

This seems to be a bug in the definition for Luhe.Exploit.PDF.B.   This does not mean other versions of AVG aren't impacted as well.  Please check your version and verify with AVG.  The current version of the virus database as of writing this diary is 3494 and was released today.  I have no confirmed report that the problem has been resolved yet AVG was aware and working on it.
 
Please share what you're seeing and update the readers.
 
Thanks goes to Heber and Tomas for sending in the information to get it out there.
 
UPDATE:
  AVG has responded to the issue and a new virus database was released earlier today.

The Pwn2Own contest by HP Tipping Point held at CanSecWest each year has a new sponsor this year. Google.

Google has offered up a bounty for breaking into Google Chrome.  As a seemingly direct defensive measure to prevent a big pay out, Google has published updates the day before the competition kicks off that fix numerous problems.

Yesterday, Google published 23 updates for the Chrome browser.  15 of them were rated high by Google.  So get those browers patched!

The nice part is Credit and Cash go to the individuals that report and assist with patch development.

Apple has also released a couple of updates today.  Apparently, they are catching up on some Java updates that Oracle released earlier.  The updates are for Mac OS X 10.5 update 9 and 10.6 update 4
