Dec 18 Adobe 0 day CVE-2009-4324 PDF attack of the Day (#5) merry christmas from uyghurhunova@yahoo.com Fri, 18 Dec 2009 11:11:27 -0800

Adobe is taking their sweet time to fix the problem while new variants show up. You don't need  ESP to predict that Christmas cards will be followed by New Year's invites and IRS forms before most people receive and install the updates. I was surprised that Symantec, being the CVE-2009-4324 pack leader in the past few days, did not detect it.  Tip of the hat to Messagelabs for catching it again.

Symantec - no luck this time :(
