As part of its twice yearly cycle of advisories, Cisco on Wednesday issued six advisories covering various components of its switches and routers. The fixes include vulnerabilities in Cisco voice products, as well as denial-of-service holes in Cisco IOS and IOS XE software, which can be exploited remotely without authentication and without end-user interaction. Cisco said that an attacker could possibly leverage some of these vulnerabilities to crash its router. The company's next update is scheduled for March 23. – GM
