Cisco fixes critical protocol flaw

Cisco has released a fix to a flaw in a popular communications protocol that some experts said could take down the Net and has announced a new, unrelated security bug.

After the United Kingdom’s National Infrastructure Security Co-ordination Centre sent out an advisory Tuesday describing the problem, Cisco and several other vendors acknowledged that their products could be affected by the flaw.
Cisco posted an alert to customers on its Web site and provided information for obtaining updated software. The problem affects a broad range of Cisco products, from its Internet Protocol routers and Ethernet switches to its optical, Internet Protocol telephony and storage products, according to the warning.
Other vendors, including Juniper Networks and Check Point Software Technologies, also have posted warnings and information regarding software updates on their Web sites.
