A heap-based buffer overflow flaw was found in the way the Skinny protocol implementation (Skinny driver) of the Asterisk, an open-source telephony toolkit processed certain protocol messages. A remote attacker could send a specially-crafted KEYPAD_BUTTON_MESSAGE event, which once processed by the Asterisk's Skinny driver would lead to asterisk executable crash, or, potentially arbitrary code execution with the privileges of the user running Asterisk.
