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
A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.

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.

Recommended fix High confidence

GnuPG 1.4.6 or later (for 1.x branch); GnuPG 2.0.2 or later (for 2.x branch)

  1. 1. Check the currently installed GnuPG version by running 'gpg --version'
  2. 2. For GnuPG 1.x users: Download and install GnuPG version 1.4.6 or later from https://www.gnupg.org/download/
  3. 3. For GnuPG 2.x users: Download and install GnuPG version 2.0.2 or later from https://www.gnupg.org/download/
  4. 4. For Ubuntu users: Run 'sudo apt-get update && sudo apt-get install gnupg' to get the latest fixed package
  5. 5. For Fedora/Enterprise Linux users: Run 'sudo yum update gnupg' or 'sudo dnf update gnupg' to apply security updates
  6. 6. Verify the installed version is fixed by running 'gpg --version' and confirming it shows 1.4.6+ or 2.0.2+
Caveat Minor - this is a security update; GnuPG maintains backward compatibility with existing keyrings
