Cisco Patches VoIP Gateway Flaws A core component of Cisco's enterprise VoIP system is vulnerable to several serious security flaws. The flaws could allow remote attackers to compromise diagram network voip a company's VoIP network, redirect or listen in on calls, says Internet Security Systems (ISS). According to an advisory issued by Cisco, successful VoIP Main Page
exploitation of the vulnerabilities may result voip network design in severe issues with Cisco CallManager and related IP telephony services. Triggering a memory allocation and buffer overflow may allow remote code execution and breach of
confidentiality. Excess memory network marketing voip allocation can cause resource starvation resulting in high CPU utilization, unresponsive terminal services, the VoIP Main Page
inability to run CCM Admin, or map drives. This may then lead to phones not voip network architecture responding, phones unregistering from the Cisco CallManager, or Cisco Call Manager restarting. CCM is the software-based call-processing component of the Cisco IP telephony solution, which extends enterprise VoIP Main Page
telephony features network solution voip and functions to packet telephony network devices such as IP phones, media processing devices, voice- over-IP (VoIP)
gateways, and multimedia applications. Cisco CallManager 3.3 and earlier, 4.0, and 4.1 network professional services voip are vulnerable to Denial of Service (DoS) attacks, memory leaks, and memory corruption which may result in services being interrupted, servers rebooting, or arbitrary code being VoIP Main Page
executed.
