Synopsis :

The remote network device is affected by multiple remote

Description :

According to the firmware version collected via SNMP, the remote
Apple Time Capsule / AirPort Base Station / AirPort Extreme Base
Station is affected by multiple remote vulnerabilities.

- An integer overflow exists in the
'netsnmp_create_subtree_cache' function that can be
exploited using a specially crafted SNMPv3 packet to
crash the SNMP server. (CVE-2008-4309)

- A remote attacker may be able to crash the racoon
daemon by sending specially crafted fragmented ISAKMP
packets, thereby triggering a NULL pointer dereference.

- By sending a large number of Router Advertisement (RA)
and Neighbor Discovery (ND) packets, an attacker on the
local network can exhaust the base station's resources,
causing it to restart unexpectedly. (CVE-2009-2189)

- An attacker with write access to an FTP server inside
the NAT may be able to use a malicious PORT command to
bypass IP-based restrictions for the service.

- If the device has been configured to act as a bridge or
configured in Network Address Translation (NAT) mode
with a default host enabled (not the default), an
attacker may be able to cause the device to stop
responding using a specially crafted DHCP reply.
