Another vulnerability in a home security firewall product : Symantec Client Firewall Remote Access and Denial of Service Issues
Basically, if you use any Norton or Symantec firewall or internet security packages, run LiveUpdate NOW. The patch is there, but you have to apply it.
This puts the Internet community in the same position as we were prior to the release of the Witty worm several weeks ago. Remember Witty? The worm that trashed the data on thousands of computers? It attacked a very similiar problem with BlackIce firewalls and wrote to random sections of the hard drive - causing random data loss, corrupted files, and unbootable systems.
