What is CVE-2015-4226?

The packet-storing capability on Cisco 9900 phones running firmware version 9.3(2) is susceptible to exploitation due to inadequate support for the RTP protocol. Remote attackers can exploit this flaw by sending malformed RTP packets after a call has been established, potentially leading to a denial of service where the device becomes unresponsive or hangs, thus disrupting normal functions.
