Internet Technology Flaws Raise Fears of DoS Attacks

摘要

The disclosure last week of two serious flaws in widely used Internet technologies raised concerns among some security experts that denial-of-service attacks could be launched against core routers and switches. But there's little reason for alarm, others maintained. One of the vulnerabilities involves Cisco Systems Inc.'s implementation of the Simple Network Management Protocol in its Internetworking Operating System. The flaw could allow remote attackers to cause vulnerable systems to repeatedly restart when processing specific SNMP requests, eventually leading to DoS conditions, Cisco said.
