CVE-2024-24194
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 · uneditedrobdns commit d76d2e6 was discovered to contain a NULL pointer dereference via the item->tokens component at /src/conf-parse.c.
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 NULL pointer dereference vulnerability exists in robdns (commit d76d2e6) within the configuration parsing logic at /src/conf-parse.c. The vulnerability occurs when attempting to access the item->tokens component without proper NULL validation, causing the application to crash when processing certain configuration inputs.

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 robdns is installedSearch for robdns binary or source code in the system using 'which robdns' or check for /src/conf-parse.c in source directoriesAffected if robdns binary or source code exists on the system
-
Determine the robdns version or commitCheck the git commit hash if using source, or look for version information in the binary using 'robdns --version' or inspecting the source repositoryAffected if The installed version corresponds to commit d76d2e6 or earlier where the vulnerable code exists
-
Verify the vulnerable code path existsInspect /src/conf-parse.c and search for code that accesses item->tokens without prior NULL validation. Look for patterns like 'item->tokens[' or 'item->tokens->' that lack preceding NULL checksAffected if The code at /src/conf-parse.c accesses item->tokens without checking if item or item->tokens is NULL first
-
Check if configuration parsing is enabledDetermine if robdns is configured to parse configuration files at startup. This is typically the default behavior; check if any config files are loaded at runtimeAffected if Robdns parses configuration files, which triggers the vulnerable code path in conf-parse.c
-
Test for crash conditionProvide a crafted configuration input that would trigger the NULL dereference and observe if the application crashes. Examine configuration inputs for conditions that could leave tokens uninitialized or NULLAffected if A configuration input causes item->tokens to be NULL when accessed, leading to a crash
A system is affected if it runs robdns from commit d76d2e6 or earlier, parses configuration files, and has code in /src/conf-parse.c that dereferences item->tokens without NULL validation.

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 dataImplement NULL pointer checks before accessing item->tokens in the configuration parsing routine to prevent dereferencing uninitialized or NULL token pointers.
