CVE-2025-15059: GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability

GIMP PSP 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 PSP 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-28232.

Security readout for executives and security teams

Plain-English summary

CVE-2025-15059 is a high-severity GIMP flaw in PSP image parsing. A malicious PSP file, or a page that causes one to be opened, could let an attacker run code as the user running GIMP. It requires user interaction and is not listed as CISA KEV in the provided data.

Executive priority

Treat this as a workstation and file-handling risk requiring timely remediation. It is not a network-worm scenario, but malicious files can be realistic in creative, marketing, support, or research workflows. Prioritize users who handle external images.

Technical view

The flaw is a heap-based buffer overflow in GIMP PSP parsing, caused by insufficient validation of user-supplied length data before copying into heap memory. The source bundle identifies GIMP 3.0.6 as affected and maps the issue to CWE-122. Successful exploitation could affect confidentiality, integrity, and availability in the current process context.

Likely exposure

Exposure is most likely on workstations or image-processing environments with GIMP 3.0.6 installed, especially where users open externally supplied PSP files. Automated or semi-automated workflows that pass PSP files into GIMP should also be reviewed.

Exploitation context

The provided sources describe remote code execution, but user interaction is required. The target must visit a malicious page or open a malicious file. The bundle does not show CISA KEV status or other cited evidence of active exploitation.

Researcher notes

Key unknowns are exact fixed upstream version details and distribution-specific package status beyond the referenced commit and Red Hat errata. Avoid assuming exploit availability. Validation should focus on version presence, PSP exposure paths, and whether vendor fixes are installed.

Mitigation direction

  • Prioritize vendor-supported GIMP updates for systems running version 3.0.6.
  • Review the GNOME commit and Red Hat advisories for fixed builds.
  • Restrict opening PSP files from untrusted or external sources.
  • Use endpoint controls to limit GIMP exposure on high-risk workstations.
  • Monitor vendor guidance for updated package status and remediation details.

Validation and detection

  • Inventory endpoints and servers for GIMP 3.0.6 installations.
  • Identify workflows that open or process PSP files with GIMP.
  • Confirm installed packages match vendor or Red Hat fixed builds.
  • Review email, browser, and file-ingest controls for PSP file handling.
  • Check vulnerability scanner results against CVE-2025-15059.
