Lifecycle Timeline
3DescriptionCVE.org
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a use-after-free vulnerability that occurs when freetype initialization fails: the method does not exit and continues to use memory that was already freed. This can be triggered during image processing and may lead to a denial of service.
AnalysisAI
Use-after-free in ImageMagick's FreeType integration path allows remote denial of service against image processing pipelines using vulnerable 6.x or 7.x releases. When FreeType initialization fails during an image processing operation, the affected code path neglects to exit cleanly and continues referencing already-freed memory, causing process corruption or crash. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker be able to supply image input that causes ImageMagick to invoke its FreeType integration code path AND that FreeType initialization fails during that invocation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L) scores 6.3 Medium, and the metric choices are informative: AC:H signals that reliably triggering the FreeType initialization failure is non-trivial and requires specific conditions, while AT:P indicates an additional attack precondition must be met beyond the attacker's direct control. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker submits a crafted image file to an internet-facing web service that passes user uploads through a vulnerable ImageMagick pipeline - for example a profile picture resize or document thumbnail generator. The crafted input is designed to invoke a FreeType-dependent operation (such as a label or annotation) under conditions that cause FreeType initialization to fail, triggering the use-after-free. … |
| Remediation | Upgrade to ImageMagick 7.1.2-26 or later (7.x branch) or 6.9.13-51 or later (6.x branch), as confirmed by the vendor security advisory GHSA-6jwg-7q3p-5fqm (https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-6jwg-7q3p-5fqm). … Detailed patch versions, workarounds, and compensating controls in full report. |
