The flaws could allow remote attackers to compromise a company's VoIP network, redirect VoIP Main Page or listen in on calls, says Internet Security Systems (ISS). According to an advisory issued by Cisco, Voip pbx phone systemsuccessful 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 allow remote code execution and breach of confidentiality. Excess memory allocation can cause resource VoIP Main Page starvation resulting in high CPU Country phone voip wiutilization, unresponsive terminal services, the inability to run CCM Admin, or map drives. This may then lead to phones not responding, phones unregistering from the Cisco VoIP Main Page CallManager, or Cisco Call Manager restarting. CCM is the software-based call-processing component of the Cisco IP telephony solution, which extends enterprise telephony features and VoIP Main Page 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 VoIP Main Page 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.
