• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes

Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, when preparing to transform from Log to sRGB colorspaces, the logmap construction fails to handle cases where the reference-black or reference-white value is larger than 1024. This leads to corrupting memory beyond the end of the allocated logmap buffer. This issue has been patched in version 7.1.2-1.

Affected products

• ImageMagick: before 7.1.2-1 — fixed in 7.1.2-1

How to fix

Upgrade to a fixed version: ImageMagick 7.1.2-1. Check the vendor advisory for mitigations.
