CVE-2017-12466
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 · uneditedCCN-lite before 2.00 allows context-dependent attackers to have unspecified impact via vectors related to ssl_halen when running ccn-lite-sim, which trigger an out-of-bounds access.
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 confidenceOut-of-bounds access vulnerability in CCN-lite before version 2.00, specifically in the ccn-lite-sim component when processing ssl_halen-related vectors. The context-dependent nature and critical CVSS score suggest potential for arbitrary code execution via memory corruption.

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.
-
Check if CCN-lite is installedLocate CCN-lite binaries or libraries on the system. Common paths include /usr/bin/ccn-lite-*, /usr/local/bin/ccn-lite-*, or check via 'which ccn-lite-sim' if the binary is in PATHAffected if CCN-lite binaries or the ccn-lite-sim component are found on the system
-
Determine the installed CCN-lite versionRun 'ccn-lite-sim -v' or 'ccn-lite-sim --version' to obtain the version number. If unavailable, check package manager listings or examine the binary metadataAffected if The version is less than 2.0.0 (e.g., 1.x.x series)
-
Identify if ssl_halen-related vectors are being processedReview application logs, configuration files, or network traffic captures for references to ssl_halen fields. Check if ccn-lite-sim is processing content with ssl_halen parametersAffected if The ccn-lite-sim component is actively processing ssl_halen-related content or vectors
-
Verify the ccn-lite-sim component is exposedInspect running processes to confirm ccn-lite-sim is executing. Check network listener status or scheduled tasks that invoke ccn-lite-simAffected if ccn-lite-sim is running as a process or service
The environment is affected if CCN-lite version is below 2.0.0 AND the ccn-lite-sim component is in use processing ssl_halen-related vectors.

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.
dbcve · scoped2.0.0
Upgrade CCN-lite to version 2.00 or later to obtain the patched code. Restrict network exposure of ccn-lite-sim until patched systems are deployed.
2.0.0 or later
- 1. Identify the current CCN-lite version by checking the installed package or binary (e.g., ccn-lite-sim -version)
- 2. Confirm the version is below 2.0.0, which is vulnerable to CVE-2017-12466
- 3. Obtain CCN-lite version 2.0.0 or later from the official repository (github.com/ccn-lite/ccn-lite)
- 4. Install the fixed version following the project's build and installation instructions
- 5. Verify the new version is installed correctly and the ccn-lite-sim binary runs without the previous out-of-bounds access issue
