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
pdns specific as packaged in Debian in version before 3.3.1-1 creates a too privileged MySQL user. It was discovered that the maintainer scripts of pdns-backend-mysql grant too wide database permissions for the pdns user. Other backends are not affected.

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
How this class of weakness works · CWE-276

Files, directories, or resources ship with permissions more open than they need to be, so unintended users can read or modify them. Attackers look for exactly these loose defaults. Remediation means tightening permissions to the minimum required and verifying them at install and at runtime.

General guidance for the incorrect default permissions class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Recommended fix High confidence

pdns-backend-mysql version 3.3.1-1

  1. 1. Check the currently installed pdns version: dpkg -l | grep pdns or apt-cache policy pdns-backend-mysql
  2. 2. Update the package repository lists: apt-get update
  3. 3. Upgrade the pdns-backend-mysql package to version 3.3.1-1 or later: apt-get install pdns-backend-mysql=3.3.1-1 or apt-get upgrade pdns-backend-mysql
  4. 4. Verify the new package version is installed: dpkg -l | grep pdns
  5. 5. If the database was previously created with overly broad permissions, review and restrict the pdns MySQL user permissions to only what is required (SELECT, INSERT, UPDATE, DELETE on the PowerDNS database tables)
  6. 6. Restart the pdns service to apply any changes: service pdns restart or systemctl restart pdns
