DescriptionCVE.org

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process). The issue is fixed in versions 7.1.2-31 and 6.9.13-56.

AnalysisAI

Memory corruption in ImageMagick's ImagesToBlob blob-conversion routine can crash an affected process on 7.x releases before 7.1.2-31 and 6.x releases before 6.9.13-56. The flaw is a use-after-free (CWE-416) in which a pointer is not updated correctly, and exploitation requires a crafted image to reach a local ImageMagick process or library call (CVSS 4.0 AV:L/AC:H/AT:P, PR:N), so no authentication is required but the attack surface is local and the trigger is difficult to satisfy reliably. …

Vulnerability AssessmentAI

Exploitation Requires the target to process an attacker-crafted/malformed image through ImageMagick's blob-conversion path (ImagesToBlob), on affected versions (before 7.1.2-31 in the 7.x line, before 6.9.13-56 in the 6.x line). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely low-priority issue despite being a memory-corruption/use-after-free class. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: upgrade to ImageMagick 7.1.2-31 (7.x line) or 6.9.13-56 (6.x line); the fixes are documented in the ImageMagick security advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-3rjr-534c-8v67, with additional detail at https://www.vulncheck.com/advisories/imagemagick-before-7.1.2-31-use-after-free-via-imagestoblob. … Detailed patch versions, workarounds, and compensating controls in full report.
