CVE-2018-19164
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 · uneditedreddcoin through 2.1.0.5 (a chain-based proof-of-stake cryptocurrency) allows a remote denial of service, exploitable by an attacker who acquires even a small amount of stake/coins in the system. The attacker sends invalid headers/blocks, which are stored on the victim's disk.
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 · moderate confidenceReddcoin through 2.1.0.5 suffers from a denial-of-service vulnerability where an attacker who has acquired even a minimal stake position in the network can send invalid headers or blocks that are accepted and stored on victims' disk, potentially consuming storage resources and disrupting service.

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 Reddcoin versionRun the version command for your reddcoind daemon (typically 'reddcoind --version' or check daemon logs/about screen)Affected if Version is 2.1.0.5 or any version <= 2.1.0.5
-
Confirm network connectivityVerify your node is connected to the Reddcoin network and accepting peer connections (check daemon network status or peer list)Affected if Node has active network connections and is syncing headers or blocks
-
Check for unvalidated block storageInspect your node's block storage directory for any recently added blocks or headers that may have been accepted without proper validationAffected if Blocks or headers exist in storage that were accepted from untrusted peers without validation errors in logs
-
Review daemon logs for invalid acceptancesSearch daemon logs for entries indicating acceptance of blocks/headers from peers, especially any that may have bypassed validation checksAffected if Logs show blocks or headers being accepted and written to disk from network peers
-
Monitor storage consumptionMonitor disk usage of the blockchain storage directory for unexpected growth that could indicate invalid data accumulationAffected if Disk usage shows unusual growth in blockchain storage files beyond expected sync behavior
Your environment is affected if you are running Reddcoin version 2.1.0.5 or lower and your node is connected to the network, as invalid blocks/headers can be accepted and stored on disk.
Generated from the published advisory. Verify against your own configuration.
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 dataThe fix requires implementing proper validation logic to reject invalid headers/blocks before they are written to disk. Users should update to any patched version released by Reddcoin developers and monitor for unusual block acceptance behavior.
