CVE-2026-42169 (GCVE-0-2026-42169)

Vulnerability from cvelistv5 – Published: 2026-08-04 03:15 – Updated: 2026-08-05 15:21

Title

Gimp: gimp apng loader heap-buffer-overflow when fctl width exceeds ihdr width (file-png.c)

Summary

A heap-buffer-overflow vulnerability exists in the APNG (Animated PNG) file loader of GIMP. This flaw occurs when the `fcTL` width exceeds the `IHDR` width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the `load_layer()` function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution.

Severity

7.3 (High)

CVE-2026-66758 (GCVE-0-2026-66758)

Vulnerability from cvelistv5 – Published: 2026-07-27 19:07 – Updated: 2026-09-02 09:33

Title

Gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted fits images

Summary

A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.

Severity

7.8 (High)

CVE-2026-66759 (GCVE-0-2026-66759)

Vulnerability from cvelistv5 – Published: 2026-07-27 19:12 – Updated: 2026-08-24 17:17

Title

Gimp: out-of-bounds read in file-icns plugin causes information disclosure or crash on crafted icns images

Summary

A flaw was found in the file-icns plugin in GIMP. When applying a decompressed mask during ICNS image processing, the plugin reads from the mask data buffer without verifying if the cursor exceeds the allocated resource size. If a crafted file contains a truncated mask resource, the icns_decompress function continues reading past the bounds of the buffer. This out-of-bounds read vulnerability results in information disclosure of heap contents, where memory contents are leaked as alpha channel pixel values, or a crash leading to a denial of service if unmapped memory is accessed.

Severity

7.1 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
