Internet Storm Center (ISC) has issued a warning about bugs in the operating system of Juniper routers. The devices are said to crash when processing malformed packets from the Net. The vendor, who is the second largest manufacturer of routers and switches worldwide – and a major Cisco competitor especially for high end routers – has released updates to close the holes.

According to ISC, JUNOS versions 7.3 to 8.4 inclusive will crash after receiving specially crafted IPv6 packets, of which no further details are available. In addition, malformed BGP packets may terminate existing BGP sessions. ISC has not stated which versions are affected by this vulnerability.

Juniper has made patches available to registered users. In JUNOS version 8.5R1, the IPv6 vulnerability is said to have been resolved.
