CVE-2020-29599

• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 7.5% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2020-12-07 · updated 2026-06-17
• Weakness: CWE-91

Description

ImageMagick before 6.9.11-40 and 7.x before 7.0.10-40 mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

Affected products

• Debian Linux: 9.0
• ImageMagick: from 6.9.8-1 before 6.9.11-40; from 7.0.5-3 before 7.0.10-40 — fixed in 6.9.11-40, 7.0.10-40

How to fix

Upgrade to a fixed version: ImageMagick 6.9.11-40, 7.0.10-40. Check the vendor advisory for mitigations.
