  (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.");

  script_tag(name:"vuldetect", value:"Checks if a vulnerable version is present on the target host.");

  script_tag(name:"insight", value:"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.

  Note: Only traffic directed to the affected system can be used to exploit this vulnerability.
  This vulnerability affects systems configured in routed and transparent firewall mode only and in
  single or multiple context mode. This vulnerability can be triggered by IPv4 traffic only. The
  attacker requires knowledge of the configured SNMP community string in SNMP version 1 and SNMP
  version 2c or a valid username and password for SNMP version 3.");
