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
The ReadPSDLayers function in coders/psd.c in ImageMagick 6.8.9.9 allows remote attackers to have unspecified impact via unknown vectors, related to "throwing of exceptions."

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

ImageMagick 6.8.9.9-4 or later, or distribution-specific patched package versions

  1. Identify the current ImageMagick version installed: `convert --version` or `apt list --installed | grep imagemagick`
  2. For Ubuntu 12.04/14.04/16.04/16.10: Run `sudo apt-get update && sudo apt-get install imagemagick` to upgrade to a patched version, or check for available security updates via `sudo apt-get upgrade`
  3. For SUSE Enterprise products (Desktop, Server, SDK, Workstation Extension 12.0): Apply the SUSE update for SUSE-SLE-SDK-12.0-2016-XXX or use `sudo zypper patch` to install security patches
  4. For OpenSUSE 13.2 and Leap 42.1: Run `sudo zypper update` or `sudo zypper patch` to apply available security updates containing the fixed ImageMagick package
  5. After upgrade, verify the fix by checking ImageMagick version: `convert --version` and confirm the version is greater than 6.8.9.9 or the patch is applied
  6. If automated updates are not available, rebuild ImageMagick from source using the upstream patch at https://anonscm.debian.org/cgit/collab-maint/imagemagick.git/commit/?h=debian-patches/6.8.9.9-4-for-upstream&id=f9ef11671c41da4cf973d0d880af1cdfbd127860
Caveat Minor - ImageMagick minor version upgrades typically have low compatibility impact, but test critical image processing workflows after upgrade
