Stack Overflow in GIMP File-PIX Plugin

Publication date: 2026-08-24

Last updated on: 2026-08-24

Assigner: redhat-SADP

Description
A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.

Executive Summary

This vulnerability is in the GIMP image editor's file-pix (ESM) plugin. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking. This causes an unbounded stack allocation followed by a 21-byte stack over-read, leading to a denial of service from stack exhaustion and limited information disclosure of stack memory contents into an intermediate file.

Detection Guidance

This vulnerability can be detected by monitoring GIMP crashes when processing PIX files or checking for stack exhaustion errors. No specific commands are provided in the resources, but users should avoid opening PIX files from untrusted sources and monitor GIMP logs for unusual behavior.

Impact Analysis

If you use GIMP to open a malicious PIX file, an attacker could cause your system to crash due to stack exhaustion. Additionally, some stack memory contents might be exposed in an intermediate file, potentially leaking sensitive information.

Compliance Impact

This vulnerability primarily impacts availability through denial of service and may cause limited information disclosure. It does not directly violate GDPR or HIPAA but could contribute to non-compliance if exploited to expose personal data or disrupt systems handling protected information.

Mitigation Strategies

Avoid opening PIX files from untrusted sources with GIMP. Update GIMP to the latest version once patches are released. Monitor GIMP logs for crashes or stack exhaustion errors when processing PIX files.
