CVE-2025-66216
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 · uneditedAIS-catcher is a multi-platform AIS receiver. Prior to version 0.64, a heap buffer overflow vulnerability has been identified in the AIS::Message class of AIS-catcher. This vulnerability allows an attacker to write approximately 1KB of arbitrary data into a 128-byte buffer. This issue has been patched in version 0.64.
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 confidenceA heap buffer overflow vulnerability exists in the AIS::Message class of AIS-catcher prior to version 0.64. The vulnerability allows writing approximately 1KB of arbitrary data into a 128-byte buffer, indicating a classic bounds-checking failure during message processing.

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.
-
Determine AIS-catcher installed versionRun the version command for AIS-catcher (typically 'aiscatcher --version' or check package manager installed version)Affected if Version is less than 0.64
-
Confirm AIS message parsing is activeCheck if AIS-catcher is configured to receive and parse AIS messages (verify input source configuration such as RTL-SDR, network feed, or other AIS input is enabled)Affected if AIS message parsing is enabled and version is below 0.64
-
Verify AIS::Message class is in useConfirm the application is processing AIS messages - this is typically active whenever AIS-catcher is running with any input sourceAffected if The application processes AIS messages and version is below 0.64
If AIS-catcher version is below 0.64 and the application is parsing AIS messages, the environment is affected by this heap buffer overflow vulnerability in the AIS::Message class.
