CVE-2026-2047: GIMP ICNS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability

GIMP ICNS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of ICNS files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28530.

Security readout for executives and security teams

Plain-English summary

CVE-2026-2047 is a high-severity GIMP flaw in ICNS image parsing. A victim must open a malicious file or visit malicious content. Successful exploitation could run attacker code with the user’s privileges, affecting confidentiality, integrity, and availability.

Executive priority

Treat this as a priority desktop software patching issue, especially for users handling external design assets, icons, or image files. No active exploitation is cited, but impact is full code execution after user interaction.

Technical view

The flaw is a heap-based buffer overflow caused by insufficient validation of user-supplied length data before copying ICNS content into heap memory. The record lists GIMP 3.0.6 and maps to CWE-122 and CWE-131, with CVSS 3.0 score 7.8.

Likely exposure

Exposure is most likely on endpoints or workstations with GIMP 3.0.6 that open ICNS or untrusted image files. Server exposure is less likely unless automated image processing uses affected GIMP components.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires user interaction: opening a malicious file or visiting a malicious page that triggers vulnerable ICNS parsing.

Researcher notes

Key unknowns remain: complete affected-version range, exact fixed release, and exploit maturity are not established in the supplied bundle. Analysis should stay anchored to ZDI, the GNOME merge request, and vendor distribution advisories.

Mitigation direction

  • Inventory GIMP installations and identify version 3.0.6 exposure.
  • Check GNOME/GIMP and distribution advisories for fixed packages or backports.
  • Apply relevant vendor or Red Hat security updates where available.
  • Restrict opening ICNS files from untrusted sources until systems are updated.
  • Remove GIMP from systems where it is not operationally required.

Validation and detection

  • Confirm installed GIMP versions across endpoint and workstation fleets.
  • Check package provenance against Red Hat RHSA-2026:4173 or applicable vendor guidance.
  • Review whether business workflows process ICNS or untrusted image files.
  • Verify patched systems no longer report the affected package version.
  • Monitor endpoint telemetry for unusual GIMP crashes during image handling.
