CVE-2025-10920

Description

A remote code execution (RCE) vulnerability exists in GIMP due to improper bounds checking during the parsing of ICNS image files. When a user opens a specially crafted ICNS file, it can trigger an out-of-bounds write, allowing attackers to execute arbitrary code within the context of the GIMP process.

Statement

This vulnerability is rated Important rather than Moderate because it enables arbitrary code execution through a memory corruption flaw in the ICNS file parser. Although exploitation requires user interaction, the underlying issue—an out-of-bounds write—directly affects memory integrity and can allow attackers to gain control of program execution. The potential for full compromise of the application process elevates its impact beyond data exposure or denial-of-service, making it a significant security concern.

Mitigation

No mitigation is currently available that meets Red Hat Product Security’s standards for usability, deployment, applicability, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Integrity

Technical Impact: Modify Memory; Execute Unauthorized Code or Commands

Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.

Other

Technical Impact: Unexpected State

Subsequent write operations can produce undefined or unexpected results.
