Cisco releases its DNS patches

Tuesday release is coordinated with those from Microsoft and others.

Following a security researcher's announcement of a massive, multivendor patch release, Cisco on Tuesday issued a patch for its products vulnerable to DNS cache-poisoning attacks.

In an advisory, Cisco cited its IOS software, Network Registrar, Application and Content Networking System, and Global Site Selector used in combination with Cisco Network Registrar among those directly affected by the vulnerability announcement.

Earlier Tuesday, Microsoft released its patch for the same DNS vulnerability.
