Cisco systems vulnerable to DoS attacks

If you or your customers are running Cisco's Unified Call Manager or Unified Presence Server, better make sure your patches are up to date. Cisco says its systems are vulnerable to DoS attacks using ping floods or malformed UDP packets. CallManager versions 3.x, 4.x and 5.0 are affected; the latest, 6.0 appears to be okay. Until you can get the patches, there are some filters you can set, too.
