CVE-2016-1369
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Adaptive Security Appliance (ASA) 5585-X FirePOWER Security Services Processor (SSP) module for Cisco ASA with FirePOWER Services 5.3.1 through 6.0.0 misconfigures kernel logging, which allows remote attackers to cause a denial of service (resource consumption, and inspection outage or module outage) via a flood of crafted IP traffic, aka Bug ID CSCux19922.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Cisco ASA 5585-X FirePOWER SSP module running ASA with FirePOWER Services versions 5.3.1 through 6.0.0 contains a kernel logging misconfiguration. Remote attackers can exploit this by sending a flood of crafted IP traffic, causing excessive resource consumption that leads to inspection outage or complete module failure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the hardware modelExecute `show version` on the ASA CLI or check the physical device labeling to confirm the model is Cisco ASA 5585-X FirePOWER SSPAffected if The hardware is not an ASA 5585-X FirePOWER SSP module
-
Verify FirePOWER Services is enabledExecute `show module` or `show module 1` within the ASA CLI to confirm the FirePOWER module is online and runningAffected if FirePOWER Services module is not installed or not running
-
Check the FirePOWER Services versionAccess the FirePOWER module CLI (session 1) and run `show version` or from ASA run `show module 1 | include Version` to retrieve the FirePOWER Services software versionAffected if The installed version matches 5.3.1, 5.3.1.1, 5.4.0, 5.4.0.1, 5.4.0.2, 5.4.0.3, 5.4.0.4, 5.4.0.5, 5.4.0.6, 5.4.1, 5.4.1.1, or 5.4.1.2
-
Confirm network exposure to untrusted trafficReview the ASA interface configurations and security policies to determine if the FirePOWER module processes traffic from untrusted networks (such as internet-facing interfaces)Affected if The module processes inspection traffic from external or untrusted network sources
You are affected if you are running a Cisco ASA 5585-X with FirePOWER Services enabled and the FirePOWER version matches one of the listed affected versions (5.3.1 through 5.4.1.2) while processing untrusted network traffic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Cisco patch for Bug ID CSCux19922 by upgrading to a fixed FirePOWER Services version (post-6.0.0). As a workaround, implement rate limiting or ingress traffic filtering at network edges to reduce the impact of traffic floods.
