CVE-2017-9098

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 3.6% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2017-05-19 · updated 2026-06-17
• Weakness: CWE-908

Description

ImageMagick before 7.0.5-2 and GraphicsMagick before 1.3.24 use uninitialized memory in the RLE decoder, allowing an attacker to leak sensitive information from process memory space, as demonstrated by remote attacks against ImageMagick code in a long-running server process that converts image data on behalf of multiple users. This is caused by a missing initialization step in the ReadRLEImage function in coders/rle.c.

Affected products

• Debian Linux: 8.0, 9.0
• GraphicsMagick: before 1.3.24 — fixed in 1.3.24
• ImageMagick: before 6.9.8-1; from 7.0.0-0 before 7.0.5-2 — fixed in 6.9.8-1, 7.0.5-2

How to fix

Upgrade to a fixed version: GraphicsMagick 1.3.24; ImageMagick 6.9.8-1, 7.0.5-2. Check the vendor advisory for mitigations.
