Vulnerability Assessment

Weakness	CWE CWE-122 ASVS 5.0 V15 - Secure Coding and Architecture Heap buffer bounds checking MITRE ATT&CK 1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	Exploitation requires the victim to run an ImageMagick X11 animate operation (the `animate`/X11 display path) on an attacker-supplied crafted image, in an environment with an X11 display available. The vector is local (AV:L) and demands user interaction (UI:P) - the attacker cannot trigger it remotely or without a user acting on the file. Impact is limited to a heap over-write that crashes the application (availability only, VA:L); the available evidence does not confirm confidentiality/integrity loss or code execution. Not applicable to deployments that do not invoke the X11 animate operation. Affected: ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33.
Impact	This is a genuinely low-to-moderate priority issue despite being a memory-corruption bug. The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L) scores 4.8 (medium) and is internally consistent with the description: the attack vector is LOCAL (AV:L), requires passive user interaction (UI:P - a user must run the X11 animate operation on the file), and the only impact is a limited availability loss (VA:L) with no confidentiality or integrity impact. The description states the overflow 'can crash the application' - evidence supports a denial-of-service/crash outcome, not confirmed code execution. There is no CISA KEV listing and no EPSS score supplied, so there is no signal of active or probable widespread exploitation; the vuln.today priority is 'this_month' (not act_now/emergency), consistent with a patch-on-normal-cycle item. No SSVC decision fields (automatable/technical impact) were provided to compare against. The references are vendor/researcher advisories (ImageMagick GHSA and VulnCheck), not verified working exploit code. Net: a real but low-urgency bug - local vector plus required user interaction and availability-only impact make this far less pressing than its CWE class (heap overflow) might suggest.
Exploit ScenarioDerived	An attacker crafts a malicious image and delivers it to a victim (e.g., via download or shared file). When the victim runs an ImageMagick X11 animate operation on that image, the heap buffer over-write corrupts memory and crashes the application. No public exploit code is identified in the provided data; the GHSA and VulnCheck entries are advisories, and the local vector plus required user interaction limit realistic impact to a crash.

AnalysisAIv1 – Oct 25, 2026

Heap buffer overflow in ImageMagick's X11 animate path (versions before 6.9.13-58 and 7.x before 7.1.2-33) allows an attacker-supplied crafted image to overwrite heap memory and crash the application when a user runs an X11 animate operation with an X11 display available. Exploitation requires local user interaction and the available assessment limits impact to availability; no public exploit was identified at time of analysis. Vendor patches are available in 6.9.13-58 and 7.1.2-33.

RemediationAI

Upgrade ImageMagick to 6.9.13-58 or later on the 6.x branch, or to 7.1.2-33 or later on the 7.x branch; the vendor advisory is https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-6p6q-wfrv-ffhh and the VulnCheck advisory is https://www.vulncheck.com/advisories/imagemagick-before-6.9.13-58-and-7-x-before-7.1.2-33-heap-buffer-overflow-via-x11-animate. For environments that cannot upgrade immediately, avoid running the X11 animate operation on attacker-supplied images; the assessment notes the issue is not applicable to deployments that do not invoke that path. No separate vendor workaround is described in the supplied sources.

Technical ContextAI · show details

ImageMagick is an image processing library and command-line toolkit; the X11 animate operation displays image sequences through an X11 display. CVE-2026-116160 is a CWE-122 heap-based buffer overflow in which a crafted image processed through that animate/X11 path can overwrite heap memory and crash the application. The supplied advisory and CPE data identify ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 as affected, and public tagging classifies the issue as a buffer overflow/heap overflow in ImageMagick; the sources do not describe the exact image parser or heap layout involved, and the assessed impact is availability only.

DescriptionCVE.org

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a heap-based buffer overflow in the X11 animate operation when processing crafted images. Attackers can supply a malicious image that, when a user runs an X11 animate operation on it, overwrites heap memory and can crash the application.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Heap Overflow HIGH

A heap overflow occurs when a program writes data beyond the bounds of a buffer allocated in the heap memory region.
