Exploitability
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
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.
What immediate steps should I take to mitigate this vulnerability?
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.
