Cisco Adaptive Security Appliance with FirePOWER Services Kernel Logging Denial 
of Service Vulnerability

Advisory ID: cisco-sa-20160504-fpkern

Revision 1.0

For Public Release 2016 May 4 16:00 UTC (GMT)

+---------------------------------------------------------------------

Summary
=======

A vulnerability in the kernel logging configuration for Firepower System 
Software for the Adaptive Security Appliance (ASA) 5585-X FirePOWER Security 
Services Processor (SSP) module could allow an unauthenticated, remote attacker 
to cause a denial of service (DoS) condition due to high consumption of system 
resources. 

The vulnerability is due to the logging of certain IP packets. An attacker 
could exploit this vulnerability by sending a flood of specially crafted IP 
packets to the affected device. An exploit could allow the attacker to cause 
the Cisco FirePOWER module to cease inspecting traffic or go offline.

Cisco has released software updates that address this vulnerability. There are 
no workarounds that address this vulnerability.
