CVE-2019-16144
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 · uneditedAn issue was discovered in the generator crate before 0.6.18 for Rust. Uninitialized memory is used by Scope, done, and yield_ during API calls.
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 confidenceThe generator Rust crate before version 0.6.18 uses uninitialized memory when calling API functions related to Scope, done, and yield_. This memory safety vulnerability could allow exposure of sensitive data from previously used memory locations, violating Rust's safety guarantees.

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.
-
Locate the generator crate in your Rust projectSearch your Cargo.toml files for 'generator' under [dependencies] or check with 'cargo tree -p generator' if the crate is a direct dependencyAffected if The generator crate appears as a direct or transitive dependency in your project
-
Identify the installed version of the generator crateRun 'cargo tree -i generator' or check the Cargo.lock file for the version entry corresponding to the generator crateAffected if The listed version is below 0.6.18 (e.g., 0.6.17, 0.6.16, etc.)
-
Verify usage of the affected API functionsSearch your Rust source files for function calls to generator::Scope, .done(), or .yield_() methods that interact with the generator crate APIAffected if Your code directly calls Scope, done, or yield_ functions from the generator crate and the crate version is below 0.6.18
-
Check for transitive dependency exposureRun 'cargo tree' to view the full dependency tree and identify if generator is pulled in as a transitive dependency by another crate, noting which crate depends on itAffected if The generator crate below 0.6.18 appears anywhere in the dependency tree regardless of direct or indirect usage
Your environment is affected if the generator crate version below 0.6.18 is present in your dependency tree and your code or any dependent crate uses the Scope, done, or yield_ API functions.

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 data0.6.18
Update the generator crate to version 0.6.18 or later to obtain the patched version that properly initializes memory before use.
