CVE-2010-4691
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 · uneditedUnspecified vulnerability on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software before 8.3(2) allows remote attackers to cause a denial of service (device crash) via multicast traffic, aka Bug IDs CSCtg61810 and CSCtg69742.
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 ASA 5500 series devices running software versions before 8.3(2) contain an unspecified vulnerability that allows remote attackers to send specially crafted multicast traffic causing the device to crash and result in a denial of service condition.

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 device modelRun 'show version' or check the device hardware label to confirm it is a Cisco ASA 5500 Series Adaptive Security ApplianceAffected if The device is not a Cisco ASA 5500 series appliance
-
Check the software versionRun 'show version' and locate the 'Cisco Adaptive Security Software (ASA)' version numberAffected if The running version is 8.3(1) or earlier, or is one of the listed 7.x versions (7.0, 7.0(0), 7.0(2), 7.0(4), 7.0(5), 7.0(5.2), 7.0(6.7), 7.0.1, 7.0.1.4, 7.0.2, 7.0.4), or if the version cannot be determined but the device is a Cisco ASA 5500 series
-
Determine if multicast traffic is processedRun 'show running-config | include multicast' or check the running configuration for any multicast-related interfaces, routing, or igmp configurationAffected if Multicast traffic handling is enabled or configured on any interface
-
Verify interface configurationRun 'show interface' to list all active interfaces and check if any are configured to process multicast trafficAffected if Interfaces are configured to accept or route multicast traffic
The device is affected if it is a Cisco ASA 5500 series running software version 8.3(1) or earlier (or any 7.x version listed) AND has multicast traffic handling enabled on any interface, as the vulnerability is triggered by specially crafted multicast packets.

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 ASA software to version 8.3(2) or later. As a temporary workaround, consider filtering or blocking unexpected multicast traffic at the network perimeter until the upgrade can be applied.
