Description
GIMP PSD File Parsing Integer 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 PSD files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28807.

CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

CVE-2026-4150 is an integer overflow vulnerability in GIMP's PSD file parsing functionality. It occurs because the software does not properly validate user-supplied data when parsing PSD files, which can lead to an integer overflow before allocating a buffer.

This flaw allows remote attackers to execute arbitrary code on affected installations of GIMP if the user interacts by opening a malicious PSD file or visiting a malicious page.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code within the context of the current process running GIMP. This means an attacker could potentially take control of the affected system, leading to unauthorized actions such as data theft, system compromise, or further malware installation.

Detection Guidance

This vulnerability involves an integer overflow in GIMP's PSD file parsing functionality triggered by opening a malicious PSD file or visiting a malicious page. Detection would primarily involve monitoring for attempts to open suspicious or untrusted PSD files with GIMP or detecting exploitation attempts involving crafted PSD files.

There are no specific commands or network detection signatures provided in the available information to detect this vulnerability directly.

Mitigation Strategies

The immediate mitigation step is to update GIMP to the latest version where this vulnerability has been fixed.

Additionally, avoid opening PSD files from untrusted or unknown sources and be cautious when visiting untrusted web pages that might trigger the vulnerability.

Compliance Impact

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.
