"According to its self-reported version, Cisco Adaptive Security Appliance Software is affected by a vulnerability in
the IP fragment-handling implementation. This allows an unauthenticated, remote attacker to cause a memory leak on an
affected device. This memory leak could prevent traffic from being processed through the device, resulting in a denial
of service (DoS) condition. The vulnerability is due to improper error handling when specific failures occur during IP
fragment reassembly. An attacker could exploit this vulnerability by sending crafted, fragmented IP traffic to a
targeted device. A successful exploit could allow the attacker to continuously consume memory on the affected device and
eventually impact traffic, resulting in a DoS condition. The device could require a manual reboot to recover from the
DoS condition. Note: This vulnerability applies to both IP Version 4 (IPv4) and IP Version 6 (IPv6) traffic.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
