• Severity: low (CVSS 3.7 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-12 · updated 2026-10-18
• Weakness: CWE-401

Description

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the GIF encoder because allocated memory is not released when color quantization fails during encoding. Attackers can supply images whose GIF conversion causes quantization to fail, leaking memory with each attempt and degrading availability.

Affected products

• ImageMagick: from 7.0.0-0 before 7.1.2-32; before 6.9.13-57 — fixed in 6.9.13-57, 7.1.2-32

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-57, 7.1.2-32. Check the vendor advisory for mitigations.
