Heap Out-of-Bounds Read in GIMP File-PVR Plugin

Publication date: 2026-08-28

Last updated on: 2026-08-28

Assigner: redhat-SADP

Description
A flaw was found in the file-pvr plugin in GIMP. When processing a specially crafted PVR image file, the VQ (compressed) decoder does not properly perform memory bounds checking. This missing validation results 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.

Executive Summary

This vulnerability is a flaw in the file-pvr plugin of GIMP. When processing a specially crafted PVR image file, the VQ decoder fails to check memory bounds, causing a heap out-of-bounds read. This can lead to application crashes, denial of service, or limited disclosure of heap memory contents.

Detection Guidance

This vulnerability can be detected by monitoring for crashes in GIMP when processing PVR image files. Check GIMP logs for heap out-of-bounds read errors or application crashes during image processing. No specific commands are provided in the context.

Impact Analysis

The impact includes application crashes causing denial of service, and potential limited exposure of sensitive heap memory data. This could affect data confidentiality if exploited.

Compliance Impact

This vulnerability could lead to information disclosure, which may violate GDPR or HIPAA requirements for protecting personal or health data. Organizations using GIMP may face compliance risks if exploited.

Mitigation Strategies

Update GIMP to the latest version to ensure the file-pvr plugin includes proper memory bounds checking. Avoid opening untrusted PVR image files until the update is applied. Monitor GIMP for crashes or unusual behavior when processing images.
