Cisco settles dispute with flaw researcher

Networking giant Cisco Systems has come to an agreement with Michael Lynn, the researcher who quit his job to be able to present a paper on security in Cisco router software.

Lynn said at a press conference Thursday that he has agreed not to talk publicly any more about the research, which outlined how attackers could take over Cisco routers and potentially bring the Internet to its knees.

He also said he had acceded to a permanent injunction imposed by a California federal court earlier Thursday in response to a motion by Cisco and Lynn's former employer, Internet Security Systems.

The organizers of the Black Hat security conference, where Lynn gave the controversial talk Wednesday, have also signed the order, according to a copy of the document seen by CNET News.com. Under the order, the management agreed to hand over videos of the session and printed copies of the paper presented.

Lynn told the press conference that he was happy to have made a move that he believed helped protect the national infrastructure.
