Heap Overflow in GIMP via Seattle Filmworks File

Publication date: 2026-08-10

Last updated on: 2026-08-10

Assigner: Red Hat, Inc.

Description
A flaw was found in the GIMP image manipulation program, specifically within its Seattle Filmworks file loader. A remote attacker could exploit this vulnerability by tricking a user into opening a specially crafted Seattle Filmworks file. This could lead to a heap overflow, allowing the attacker to write several kilobytes of controlled data beyond the intended memory buffer. Such an overflow can result in memory corruption, potentially leading to arbitrary code execution or a denial of service.

Executive Summary

This vulnerability is a heap overflow flaw in the GIMP image manipulation program's Seattle Filmworks file loader. An attacker can exploit it by tricking a user into opening a specially crafted Seattle Filmworks file. This causes the program to write several kilobytes of controlled data beyond the intended memory buffer, leading to memory corruption that may allow arbitrary code execution or a denial of service.

Detection Guidance

Detecting this vulnerability requires checking for GIMP installations and monitoring for suspicious Seattle Filmworks (.sfw) file processing. Inspect GIMP versions with 'gimp --version' and check loaded modules with 'gimp -l'. Monitor system logs for crashes during image processing or unusual memory errors.

Impact Analysis

If exploited, this vulnerability could allow an attacker to execute arbitrary code on your system or cause GIMP to crash, leading to a denial of service. It specifically targets the Seattle Filmworks file loader, so opening untrusted .sfw files is the primary risk vector.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards. It is a technical flaw in GIMP's file handling that could lead to arbitrary code execution or denial of service. Compliance impacts would only occur if the vulnerability were exploited to access, modify, or destroy regulated data, which is not specified in the provided context.

Mitigation Strategies

Immediately stop opening Seattle Filmworks (.sfw) files from untrusted sources. Update GIMP to the latest patched version if available. If updates are unavailable, consider removing the Seattle Filmworks loader module or disabling GIMP's file loader functionality for .sfw files.
