Cisco has released eight security updates for the Internetwork Operating System (IOS) software used to power its routers.
The patches were released Wednesday, the day Cisco had previously scheduled for its twice-yearly IOS updates. None of the bugs had been publicly disclosed ahead of Wednesday’s updates, but some of them were reported to Cisco by outside sources.
Most of the bugs could be exploited by attackers to crash or somehow disrupt service to a router, typically if a specific, vulnerable service is enabled, Cisco said.
The eight updates fix 11 security vulnerabilities, according to Jean Reese, senior manager with Cisco’s Product Security Incident Response Team.
