voip skypeInternet telephony voipCisco 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 a company's VoIP network, redirect or listen in VoIP Main Page on calls, says Internet Security Systems (ISS). According Source voipto an advisory issued by Cisco, successful exploitation of the vulnerabilities may result in severe issues with Cisco CallManager and related IP telephony services. VoIP Main Page Triggering a memory allocation and buffer overflow may allow remote code execution and breach of confidentiality. Excess memory allocation can cause resource starvation resulting in high CPU utilization, unresponsive terminal services, the skype voip inability to run CCM Admin, or map drives. This may then lead VoIP Main Page to phones Voip networknot 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 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 are vulnerable to Denial of Service (DoS) attacks, memory leaks, and memory corruption which may result VoIP Main Page in services being interrupted, servers rebooting, or arbitrary code being executed.
