CVE-2017-12469
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 · uneditedBuffer overflow in util/ccnl-common.c in CCN-lite before 2.00 allows context-dependent attackers to have unspecified impact by leveraging incorrect memory allocation.
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 confidenceA buffer overflow vulnerability exists in util/ccnl-common.c of CCN-lite versions prior to 2.00, caused by incorrect memory allocation. The vulnerability has a critical CVSS score of 9.8, indicating potential for severe impact including remote code execution, though the exact exploitation details are context-dependent.

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.
-
Verify CCN-lite installationCheck if CCN-lite is present on the system by searching for executables (ccn-lite-*) or libraries related to CCN-lite using commands like 'which ccn-lite-*' or 'find /usr -name "*ccn*" 2>/dev/null'Affected if CCN-lite is not found on the system - the CVE does not apply
-
Identify CCN-lite versionRun 'ccn-lite-ctrl -v' or 'ccn-lite-relay -v' to display the installed version. If these commands are not available, check package management tools (dpkg, rpm, pip) or examine source directories for version informationAffected if The displayed version is below 2.0.0 (e.g., 1.x.x or earlier)
-
Locate vulnerable source fileIf CCN-lite was built from source, search for the file util/ccnl-common.c in the installation or source tree using 'find . -name ccnl-common.c'Affected if The file exists and the associated CCN-lite binary/library is version 2.0.0 or later, but the source was not patched - compare version in step 2 first
-
Confirm runtime usage of vulnerable componentReview application logs, process lists, or configuration files to determine if CCN-lite utilities (ccn-lite-ctrl, ccn-lite-relay, ccn-lite-srv) are actively running or configured as servicesAffected if CCN-lite version is below 2.0.0 AND the utility binaries or libraries from util/ccnl-common.c are in active use
A user is affected if CCN-lite version 1.x.x or any version below 2.0.0 is installed and the ccn-lite utilities or libraries are in use on the system.

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
Update CCN-lite to version 2.00 or later to remediate the buffer overflow vulnerability caused by incorrect memory allocation. Given the critical severity, prioritize this update in deployment cycles.
CCN-lite 2.0.0
- 1. Check the currently installed CCN-lite version by running 'ccn-lite-version' or checking the package manager
- 2. Download CCN-lite version 2.0.0 or later from the official GitHub repository: https://github.com/ccn-lite/ccn-lite
- 3. If using a package manager, update to the latest version (e.g., 'apt-get update && apt-get install ccn-lite' or equivalent)
- 4. If building from source, clone the repository and checkout tag 'v2.0.0' or later: 'git clone https://github.com/ccn-lite/ccn-lite.git && cd ccn-lite && git checkout v2.0.0'
- 5. Rebuild and reinstall CCN-lite following the build instructions in the README
- 6. Verify the installed version is 2.0.0 or later
