CVE-2026-2271: Gimp: gimp: denial of service via crafted psp image file

A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation could result in an application level denial of service.

Security readout for executives and security teams

Plain-English summary

CVE-2026-2271 is a low-severity GIMP flaw triggered by a specially crafted Paint Shop Pro image file. If a user opens the file, GIMP can crash, causing application-level denial of service. The sources do not indicate data theft, system takeover, or active exploitation.

Executive priority

Handle through routine patch management unless your organization processes untrusted image files at scale. Business risk is limited to user disruption and potential workflow interruption. No evidence in the provided sources supports emergency response.

Technical view

GIMP’s PSP parser has an integer overflow in read_creator_block(). A 32-bit length value from the file is used for memory allocation without proper validation, leading to heap overflow and out-of-bounds write. CVSS 3.1 is 3.3, with local attack vector and required user interaction.

Likely exposure

Exposure is most relevant where GIMP is installed and users may open untrusted PSP files. Red Hat lists gimp as affected on RHEL 7, RHEL 8, and RHEL 9; RHEL 6 status is unknown in the provided data.

Exploitation context

An attacker would need to get a crafted PSP image opened in GIMP. The provided sources do not list public exploitation, and CISA KEV status is false. Expected impact is application crash or limited availability loss, not confirmed code execution.

Researcher notes

Key constraints are user interaction and PSP file parsing reachability. Sources describe integer overflow leading to heap overflow and out-of-bounds write, but only application-level denial of service is claimed. No fixed version, patch commit, or exploit-in-the-wild evidence is provided here.

Mitigation direction

  • Check Red Hat and GIMP guidance for fixed packages or advisories.
  • Avoid opening PSP files from untrusted or unexpected sources.
  • Limit GIMP use on systems processing externally supplied image files.
  • Prioritize updates through normal desktop and workstation patch cycles.

Validation and detection

  • Inventory systems with GIMP installed, especially RHEL 7, 8, and 9.
  • Confirm installed GIMP package versions against vendor advisories.
  • Review helpdesk or endpoint telemetry for repeated GIMP crashes after opening PSP files.
  • Track the GNOME GIMP issue and Red Hat Bugzilla for remediation status.
