CVE-2026-106064 · Severity: medium · CVSS 6.3 · Published 2026-10-07

GIMP, a widely-used image editing application, contains a flaw in its GIF export function that can cause a crash or memory corruption when exporting images with extremely large dimensions. An attacker or user exporting a maliciously-crafted high-resolution image could trigger the overflow, leading to application failure or potential data corruption.

## Quick answers

**Is CVE-2026-106064 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-106064 being exploited in the wild.

**How severe is CVE-2026-106064?** Medium severity, with a CVSS score of 6.3, published 7 October 2026.

**Which products and versions are affected?** GIMP GIMP.

**Is there a fix for CVE-2026-106064?** No fixed version is recorded yet. Do not export untrusted high-resolution images to GIF; enforce maximum width and height limits in batch or scripted export pipelines. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.

**How is CVE-2026-106064 attacked?** It is attacked with local access, in a software library.

**Am I affected by CVE-2026-106064?** Check whether you run Gimp. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix


Do not export untrusted high-resolution images to GIF; enforce maximum width and height limits in batch or scripted export pipelines.

## Technical details

A heap-based buffer overflow exists in GIMP's GIF export plug-in due to 32-bit integer overflow when computing pixel buffer size. The plug-in allocates a buffer based on the wrapped overflow value while GEGL writes using the true image extent, causing out-of-bounds writes. Exploitation requires user interaction (performing a GIF export on an oversized image), and yields memory corruption, denial of service, or potential code execution.
