DescriptionCVE.org

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-28874.

AnalysisAI

Heap-based buffer overflow in GIMP's PSP (Paint Shop Pro) file parser enables remote code execution when processing malicious PSP image files. Unauthenticated attackers can execute arbitrary code with user privileges by convincing targets to open crafted PSP files. CVSS 7.8 (High) reflects local attack vector requiring user interaction. No public exploit identified at time of analysis. Vulnerability tracked as ZDI-CAN-28874 by Zero Day Initiative.

Technical ContextAI

CWE-122 heap overflow during PSP file parsing operations. Insufficient length validation before copying user-controlled data to heap-allocated buffer. CPE cpe:2.3:a:gimp:gimp applies broadly across GIMP versions pending vendor-specific version disclosure. Attack succeeds through malformed PSP file structure manipulation targeting heap memory.

RemediationAI

Vendor-released patch: GIMP upstream commit 98cb1371fd4e22cca75017ea3252dc32fc218712 addresses the vulnerability. Users should update to GIMP versions incorporating this commit through distribution package managers or official GIMP releases. SUSE users apply SUSE-SU-2026:1193 security update via zypper/YaST. Until patching, avoid opening PSP files from untrusted sources and disable PSP file format support if not operationally required. Verify patch deployment: https://gitlab.gnome.org/GNOME/gimp/-/commit/98cb1371fd4e22cca75017ea3252dc32fc218712 and distribution-specific advisories at https://www.suse.com/support/update/SUSE-SU-2026:1193/.
