“A vulnerability in the Simple Network Management Protocol (SNMP) code of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause a reload of the affected system or to remotely execute code.
The vulnerability is due to a buffer overflow in the affected code area. An attacker could exploit this vulnerability by sending crafted SNMP packets to the affected system. An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system. The attacker must know the SNMP community string to exploit this vulnerability.”
