ZDI-26-459: GIMP SGI 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 ZDI has assigned a CVSS rating of 7.8. The following CVEs are assigned: CVE-2026-18306.
AI Analysis
Technical Summary
CVE-2026-18306 is an integer overflow vulnerability in the SGI file parser of GIMP. The vulnerability occurs due to insufficient validation of user input, which can cause an integer overflow prior to memory write operations. Exploitation requires user interaction, such as opening a crafted SGI file or visiting a malicious page, enabling remote code execution within the context of the GIMP process. The Zero Day Initiative assigned a CVSS score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). GIMP has issued an official update that fixes this vulnerability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the user running GIMP. This can lead to full compromise of the affected system or user environment. The vulnerability requires user interaction but has high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
An official fix is available from GIMP. Users should update to the latest version containing the patch referenced in the vendor's advisory (commit 76531da9732f38566e5fd8f8f80c837158511ae5). Applying this update mitigates the vulnerability. No additional mitigations are specifically required beyond applying the vendor-provided patch.
