CVE-2018-1000892
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 · uneditedBitcoin SV before 0.1.1 allows uncontrolled resource consumption when receiving sendheaders messages.
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 confidenceBitcoin SV before version 0.1.1 contains a vulnerability where processing incoming sendheaders protocol messages can lead to uncontrolled resource consumption. The sendheaders message is a Bitcoin P2P protocol message used to request headers instead of inventory announcements. Without proper resource limits, an attacker could flood a node with these messages to exhaust memory or CPU, causing a denial of 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 if Bitcoin SV is installedRun 'bitcoind -version' or 'bitcoin-cli version' to check for Bitcoin SV daemon, or inspect running processes with 'ps aux | grep bitcoind'Affected if Bitcoin SV daemon is running and responds to version queries
-
Determine the installed Bitcoin SV versionExecute 'bitcoind -version' or 'bitcoin-cli getnetworkinfo' and locate the 'version' or 'subversion' field in the outputAffected if The reported version is below 0.1.1 (e.g., 0.1.0 or earlier)
-
Verify P2P network listening is enabledCheck bitcoin.conf for 'listen=1' (default) or run 'bitcoin-cli getnetworkinfo' and check if 'localaddresses' or 'listening' is trueAffected if The node is configured to accept incoming P2P connections (listen mode is enabled)
-
Confirm the node accepts external P2P connectionsRun 'bitcoin-cli getnetworkinfo' and examine the 'networkactive' and connection settings, or review P2P bind addresses in the configurationAffected if The node has active P2P network participation with external peers
You are affected if Bitcoin SV is running with a version below 0.1.1 and the node has P2P network listening enabled, as this allows the sendheaders message to be processed.

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 data0.1.1
Upgrade Bitcoin SV to version 0.1.1 or later to obtain the patch for this vulnerability. If immediate upgrade is not possible, consider network-level restrictions on P2P connections from untrusted peers.
