CVE-2017-6499 Debian CVE debrief

CVE-2017-6499 is a denial-of-service issue in Magick++ for ImageMagick 6.9.7. According to NVD, a specially crafted file can create a nested exception that leads to a memory leak, which can exhaust resources and disrupt service availability. NVD rates the issue as CVSS 3.0 5.5 (Medium) with availability impact high. Debian references the issue in DSA-3808, and the ImageMagick project published a patch commit and vendor advisory.

Who should care

Teams operating ImageMagick or Magick++ in file-processing pipelines should prioritize this, especially Debian 8.0/9.0 environments and any deployment explicitly using ImageMagick 6.9.7. Service owners should care most where untrusted files are accepted or automated image processing is exposed to users.

Technical summary

NVD lists the vulnerable component as ImageMagick 6.9.7 and identifies CWE-772. The CVSS vector is AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, indicating the issue requires user interaction and primarily affects availability. The reported behavior is a nested exception path that can leak memory when processing a specially crafted file, potentially causing denial of service.

Defensive priority

Medium

Recommended defensive actions

  • Apply the vendor patch or update to a fixed ImageMagick/Magick++ release referenced by the ImageMagick commit and advisory.
  • If you use Debian 8.0 or 9.0 packages, review and apply Debian security guidance in DSA-3808.
  • Inventory systems using ImageMagick 6.9.7 or Magick++ and prioritize internet-facing or automated upload-processing services.
  • Test file-processing workflows for abnormal memory growth and restart behavior after malformed inputs.
  • Use least-privilege service accounts and resource controls to reduce blast radius from resource-exhaustion failures.

Evidence notes

Primary evidence comes from NVD and linked advisories.
