Use-After-Free in GIMP XCF Loader via Crafted File

Publication date: 2026-10-19

Last updated on: 2026-11-04

Assigner: redhat-SADP

Description

A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a crash and potentially arbitrary code execution.

Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free flaw in GIMP's XCF file loader. When a crafted XCF file is opened, the software fails to properly handle linked channels, leaving a dangling pointer. This can lead to memory corruption, causing a crash or potentially allowing arbitrary code execution in the main GIMP process.

Detection Guidance

This vulnerability involves a use-after-free issue in GIMP when processing crafted XCF files. Detection primarily involves monitoring for crashes or unusual behavior when opening XCF files in GIMP. Ensure GIMP is updated to the latest version and check for any patches addressing this issue. No specific network detection commands are provided.

Impact Analysis

If exploited, this vulnerability could allow an attacker to execute arbitrary code on your system by tricking you into opening a specially crafted XCF file. This could lead to system compromise, data theft, or further malware installation. Even without exploitation, it may cause GIMP to crash repeatedly.

Compliance Impact

This vulnerability could potentially lead to arbitrary code execution, which may result in unauthorized access to sensitive data. This could impact compliance with GDPR (data protection) and HIPAA (health information privacy) by exposing personal or health-related data.

Mitigation Strategies

Update GIMP to the latest version to patch the flaw. Avoid opening untrusted XCF files until patched. Monitor for crashes or unusual behavior when processing images.
