Vulnerability Assessment

V15 - Secure Coding and Architecture Recursion depth limits
|
| Exploitation Conditions | Exploitation requires that ImageMagick be running with the DNG decoder disabled - a non-default configuration explicitly named by the vendor advisory - and that the attacker get a crafted TIFF image processed by the application. Impact is limited to a process crash (availability only; no data disclosure or modification). The high attack complexity and attack requirements (AC:H/AT:P) in the CVSS 4.0 vector indicate the crash is not trivially or reliably triggerable, and the non-default DNG-disabled requirement further narrows the exposed population. Affected: all versions before 7.1.2-34; fixed in 7.1.2-34. |
| Impact | Signals align on moderate, not urgent, priority. The supplied CVSS 4.0 vector (6.3, medium) shows network vector but AC:H and AT:P (attack complexity high, attack requirements present) and an impact limited to VA:L - availability only, no confidentiality or integrity loss. This is a denial-of-service crash, not code execution, consistent with CWE-674 (uncontrolled recursion / stack exhaustion). The vuln.today decision label is 'this_month', not act_now or emergency. This is NOT in CISA KEV, so there is no confirmed active exploitation, and no EPSS probability was provided in the input, so widespread-exploitation likelihood cannot be quantified from this data. The two references are vendor/analyst advisories (ImageMagick GHSA and VulnCheck), not verified working exploit code, so no public exploit is confirmed. A further limiting factor is the trigger condition stated by the vendor: the flaw occurs specifically when the DNG decoder is disabled, a non-default deployment choice. Net: a genuine but medium DoS issue in very widely deployed software - worth patching on a normal monthly cycle rather than as an emergency, with real-world risk bounded by the non-default configuration requirement and the availability-only impact. |
| Exploit ScenarioDerived | An attacker supplies a crafted TIFF image to a service or workflow that processes images with ImageMagick configured with the DNG decoder disabled; parsing the file triggers a stack overflow that crashes the process, causing denial of service. The exact triggering mechanism beyond 'crafted image' is not detailed in the available sources (CWE-674 implies uncontrolled recursion). No public exploit is identified at time of analysis, and the high attack complexity / attack requirements (AC:H/AT:P) suggest the condition is not trivially reliable. |

Alert meAnalysisAIv1 – Oct 29, 2026
Stack overflow in ImageMagick's TIFF decoder can crash the process when a crafted TIFF image is processed and the DNG decoder is disabled, producing a denial of service. All ImageMagick versions before 7.1.2-34 are affected, and the vendor-released fix is 7.1.2-34; the prerequisite is a non-default configuration, and the CVSS 4.0 vector's high attack complexity and attack requirements indicate the crash is not trivially or reliably triggerable. No CISA KEV entry or confirmed public exploit code was identified at time of analysis, and the priority signal is this_month rather than emergency.
RemediationAI
Vendor-released patch: 7.1.2-34. Upgrade ImageMagick to 7.1.2-34 or later; the vendor advisory is https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-g5j8-ff59-wp88 and the VulnCheck advisory is https://www.vulncheck.com/advisories/imagemagick-before-7.1.2-34-stack-overflow-in-tiff-decoder. No vendor workaround is documented. Because exploitation requires the DNG decoder to be disabled and a crafted TIFF to be processed, organizations that cannot upgrade immediately should block untrusted TIFF files from reaching ImageMagick at the application or upload boundary; re-enabling the DNG decoder is not documented as a remediation and would change decoder exposure.

Technical ContextAI · show details
The issue is in ImageMagick's TIFF decoding path and is classified as CWE-674 (Uncontrolled Recursion), which causes stack exhaustion and a crash. The exact crafted-TIFF structure and recursion path are not described in the available sources; the advisory only states that a crafted image can trigger the stack overflow when the DNG decoder is disabled. The affected CPE cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:* covers all versions before 7.1.2-34. The DNG-disabled requirement is a non-default deployment mode, and the independent assessment's CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L and the CVSS 4.0 AC:H/AT:P metrics both frame this as a difficult-to-trigger availability-only crash rather than a reliable remote denial of service across default installations.

Lifecycle Timeline
2DescriptionCVE.org
ImageMagick before 7.1.2-34 contains a stack overflow vulnerability in the TIFF decoder that occurs when the DNG decoder is disabled. Attackers can supply a crafted image file for processing to trigger the stack overflow and crash the application, causing denial of service.
