Avast 4.8.1356 hackable???

I just read this???

http://msmvps.com/blogs/donna/archive/2009/10/26/avast-local-privilege-escalation-and-dos-vulnerabilities-no-plan-to-fix-vuln-2-for-avast-v4-users-but-will-fix-it-in-avast-v5.aspx

Is there any base to these claims??

Best wishes,

No 1 is fixed in the latest build of avast! 4.8 I believe, and No 2 is ridiculous; the 400.vps file is, just as any other avast! files, protected by avast! self-defense.

GUYS THIS NEWS is old??!!
