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