CVE-2026-82328: Gimp

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

A flaw was found in the file-ico plugin in GIMP. When processing a specially crafted ICO image file, the plugin does not properly validate the used_clrs (palette count) parameter. This incorrect validation leads to improper memory bounds checking, resulting in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.

Affected products

• Gimp Gimp: up to and including 3.3.1
• Red Hat Enterprise Linux: version 6.0 only; version 7.0 only; version 8.0 only; version 9.0 only
