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 · unedited
rPGP is a pure Rust implementation of OpenPGP. Prior to 0.14.1, rPGP allows attackers to trigger resource exhaustion vulnerabilities in rpgp by providing crafted messages. This affects general message parsing and decryption with symmetric keys.

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 confidence

rPGP versions prior to 0.14.1 contain resource exhaustion vulnerabilities that can be triggered by processing crafted OpenPGP messages. Attackers can exploit this during general message parsing and symmetric key decryption operations, potentially causing denial of service.

MitigationUpgrade rPGP to version 0.14.1 or later to patch the resource exhaustion vulnerabilities in message parsing and symmetric key decryption.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify rPGP usage
    Search project dependencies (Cargo.toml, lock files, or package manifests) for the rPGP crate or library
    Affected if rPGP is present as a dependency
  2. Check rPGP version
    Examine the Cargo.lock file or dependency tree for the installed rPGP version number
    Affected if Version is below 0.14.1 (e.g., 0.13.x, 0.12.x, etc.)
  3. Determine if OpenPGP message parsing is in use
    Review application code to identify if any functions process incoming or file-based OpenPGP messages
    Affected if The application parses OpenPGP messages from untrusted sources
  4. Determine if symmetric key decryption is used
    Review application code for OpenPGP symmetric decryption operations, particularly with user-supplied keys
    Affected if The application performs symmetric key decryption on OpenPGP messages

You are affected if rPGP version below 0.14.1 is installed AND your application processes OpenPGP messages from untrusted sources or performs symmetric key decryption operations.

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.
