Flaws threaten VoIP networks

Wednesday, 14 January 2004, 3:08 AM EST

The flaws affect software and hardware that support the real-time multimedia communications and processing standard, known as the International Telecommunications Union (ITU) H.323 standard.

The security problems can cause a product that supports H.323 to crash. For example, in Cisco telecommunications products running its IOS operating system, the vulnerability could be used to cause the devices to freeze or reboot. However, on Microsoft's Internet Security and Acceleration Server 2000, which is included with Small Business Server 2000 and 2003 editions, the vulnerability could allow an attacker to take control of the system.

Ironically, in Microsoft's case, the Internet Security and Acceleration Server is designed to help protect companies' networks from online attacks. Specifically, a filter used in the server that secures VoIP communications is vulnerable to the flaw.
