Cisco releases security patch amid controversy

Security officials at Cisco Systems released a patch to fix a now notorious security problem. The release comes one day after Cisco Systems slapped a restraining order on a security researcher for disclosing details of a flaw in Cisco's network software. Cisco and Internet Security Systems (ISS) on Thursday filed for, and received, a permanent injunction against Michael Lynn, a former ISS researcher, and Black Hat, the company hosting the popular Black Hat Conference. IOS is the network infrastructure software used in everything from Cisco's home office routers to those used in enterprise and ISP networks. IOS is used in more than 10 million devices worldwide.
