DescriptionCVE.org

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.

AnalysisAI

GIMP's PSP file parser fails to validate 32-bit length values in the read_creator_block() function, allowing local attackers to trigger integer overflow and heap buffer overflow via specially crafted PSP image files, resulting in application-level denial of service. Red Hat Enterprise Linux versions 6-9, Ubuntu (7 releases), Debian (9 releases), and SUSE are affected. No public exploit code or active exploitation has been identified at the time of analysis, though the vulnerability has been assigned ENISA EUVD ID EUVD-2026-16340 and tracked across major Linux distributions.

Technical ContextAI

GIMP's PSP (Paint Shop Pro) file format parser contains a vulnerability in the read_creator_block() function, which is responsible for parsing metadata blocks within PSP image files. The vulnerability stems from CWE-190 (Integer Overflow or Wraparound), specifically the failure to validate a 32-bit length field before using it in a memory allocation operation. When a crafted PSP file provides a maliciously large length value, the integer overflow during size calculation results in undersized heap buffer allocation. Subsequent writes to the buffer then cause a heap-based buffer overflow (CWE-122), leading to memory corruption and application crash. The affected products include GIMP on Red Hat Enterprise Linux versions 6, 7, 8, and 9 (identified via CPE: cpe:2.3:a:red_hat:red_hat_enterprise_linux_6-9), as well as distributions tracked by Ubuntu (7 releases) and Debian (9 releases with advisories DLA-4483-1 and DSA-6139-1). This is a classic file format parsing vulnerability requiring user interaction to open a malicious file.

RemediationAI

Apply security updates provided by your Linux distribution vendor. For Red Hat Enterprise Linux, consult https://access.redhat.com/security/cve/CVE-2026-2271 for version-specific patches. For Debian-based systems, review advisories DLA-4483-1 (Debian LTS) and DSA-6139-1 (stable/testing); for SUSE, apply SUSE-SU-2026:0604. Until patches can be deployed, restrict file upload and file-open capabilities for GIMP to trusted sources only, disable automatic file associations for PSP files in untrusted contexts, and consider running GIMP in a sandboxed environment (e.g., Flatpak, containers, or dedicated user accounts with minimal privileges) if processing untrusted image files is unavoidable. Monitor bugzilla.redhat.com (bug #2438429) and Debian security-tracker for updated advisories.
