CVE-2026-18304: GIMP TIF File Parsing Integer Overflow Remote Code Execution Vulnerability
GIMP TIF 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 TIF 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-29403.

Frequently Asked Questions
What must an attacker do to exploit this issue?
An attacker must persuade a user to visit a malicious page or open a malicious TIF file. Exploitation occurs during TIF parsing and can execute arbitrary code in the context of the current GIMP process.
Does exploitation require prior access or elevated privileges?
No prior privileges are required. However, exploitation requires local attack-vector conditions and user interaction.
What type of files or workflows should be treated as risky?
Treat untrusted TIF files and web content that may cause GIMP to process a TIF file as potentially dangerous. The vulnerability is triggered by malformed user-supplied data during TIF parsing.
