Cisco issues patches for IOS bugs

Cisco released eight security updates in its latest IOS patch, which the company issues twice a year. The eight updates fix 11 security vulnerabilities, most of which could disable tor disrupt service on a router, according to a report by IDG News Service's Robert McMillan.

Cisco has also been working with other companies on a remedy for "Sockstress" bug in TCP/IP. This can be exploited for low-bandwidth DoS attacks.

Cisco's next set of IOS patches is due Sept. 23, according to McMillan's report.
