Cisco patch day closes critical vulnerabilities
Cisco has published ten security advisories as part of its bi-annual patch day. The advisories resolve a number of security vulnerabilities. The most serious vulnerability (CVSS 10) to have been addressed was in Catalyst switches running the company's iOS network operating system software. A bug in the Smart Install remote maintenance feature allowed remote attackers to execute arbitrary code on affected switches.
