CVE-2013-3410
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 · uneditedCisco Intrusion Prevention System (IPS) Software on IPS NME devices before 7.0(9)E4 allows remote attackers to cause a denial of service (device reload) via malformed IPv4 packets that trigger incorrect memory allocation, aka Bug ID CSCua61977.
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 confidenceCisco IPS Software on IPS NME devices before version 7.0(9)E4 contains a memory allocation flaw triggered by malformed IPv4 packets. When processing these specially crafted packets, the software performs incorrect memory allocation leading to a device reload (Denial of Service). This vulnerability is remotely exploitable without authentication.

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 device typeConfirm the device is a Cisco IPS NME (Network Module Enhanced) device by checking the hardware model or running 'show version' to identify the platform as an NME moduleAffected if The device is not an IPS NME device, then it is not affected by this specific CVE
-
Check Cisco IPS Software versionRun 'show version' or 'show module' command on the device to display the installed Cisco IPS Software versionAffected if The installed version is 7.0(8)e4 or lower, or matches any of these affected versions: 7.0, 7.0(1)e3, 7.0(2)e3, 7.0(2)e4, 7.0(3)e4, 7.0(4)e4, 7.0(5a)e4, 7.0(6)e4, 7.0(7)e4, or 7.0(8)e4
-
Verify IPS is configured and activeRun 'show ip ips' or 'show configuration | include ips' to confirm the Intrusion Prevention System is configured to inspect IPv4 trafficAffected if IPS is actively processing IPv4 packets; the vulnerability is triggered when the device processes specially crafted IPv4 packets through the IPS inspection engine
The environment is affected if the device is a Cisco IPS NME running Cisco IPS Software version 7.0(8)e4 or lower (including any version from 7.0 through 7.0(8)e4), with IPS enabled to process IPv4 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 dataUpgrade Cisco IPS Software on affected NME devices to version 7.0(9)E4 or later. During the upgrade, schedule a maintenance window as the device will reload during the update.
