Cisco Patches 'Black Hat' IOS Flaw

thursnick writes "eWeek is reporting that Cisco has finally issued a comprehensive fix for a critical IOS vulnerability that set off a firestorm of controversy at the Black Hat Briefings earlier this year. The patches come more than three months after former ISS researcher Michael Lynn quit his job to present the first-ever example of exploit shellcode in Cisco IOS (Internetwork Operating System), a presentation that landed him in legal hot water. Cisco's advisory effectively confirmed Lynn's summer warning that the flaw could be exploited by remote attackers to execute arbitrary commands or cause a denial-of-service on compromised routers."
