CVE-2016-8862 Imagemagick CVE debrief

CVE-2016-8862 affects ImageMagick’s AcquireMagickMemory path in MagickCore/memory.c. According to the NVD record, a crafted image can trigger a memory allocation failure and produce unspecified impact. The issue was publicly discussed in October 2016 and published in the CVE/NVD record on 2017-02-15. NVD marks the weakness as CWE-119 and assigns a high-severity CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

Who should care

Organizations that process untrusted images with ImageMagick, especially internet-facing services, document processing pipelines, thumbnailers, and applications embedding ImageMagick libraries. Administrators of affected Linux distributions and package consumers should also check vendor backports and advisories.

Technical summary

The vulnerable condition is in AcquireMagickMemory, where processing a crafted image can lead to a memory allocation failure. The official NVD record lists affected ImageMagick ranges before 6.9.4-0 and from 7.0.0-0 through before 7.0.3-3, plus a Debian 8.0 CPE entry. The source description does not specify a single concrete end effect beyond "unspecified impact," but the CVSS and CWE mapping indicate a memory-safety issue with potentially severe consequences.

Defensive priority

High. Image processing components often accept externally supplied files, so even user-interaction-required issues can be reachable in common upload, preview, and conversion workflows. Prioritize patching or replacing vulnerable ImageMagick builds and validating distro backports.

Recommended defensive actions

  • Upgrade ImageMagick to a fixed release at or beyond 7.0.3-3, or to the vendor-maintained package version that includes the fix.
  • If you rely on distribution packages, verify whether your vendor has backported the fix rather than comparing only upstream version numbers.
  • Restrict or sandbox image conversion services that accept untrusted files, since the attack path is triggered by crafted images.
  • Review application flows that automatically process uploaded or downloaded images and ensure they are covered by patch management and isolation controls.
  • Monitor the cited vendor and issue-tracking references for package-specific remediation notes and confirm deployed versions after updating.

Evidence notes

All claims are grounded in the supplied NVD record and linked references. The NVD description states that AcquireMagickMemory in MagickCore/memory.c is triggered by a crafted image and leads to a memory allocation failure with unspecified impact. The NVD CPE criteria identify vulnerable ImageMagick ranges before 6.9.4-0 and before 7.0.3-3. The record also maps the issue to CWE-119 and CVSS:3.1 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.
