ZDI-26-461: 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 ZDI has assigned a CVSS rating of 7.8. The following CVEs are assigned: CVE-2026-18308.
AI Analysis
Technical Summary
CVE-2026-18308 is a high-severity remote code execution vulnerability in GIMP affecting the parsing of TIF files. The flaw arises from an integer overflow triggered by insufficient validation of user input before buffer allocation. An attacker can exploit this by convincing a user to open a crafted malicious TIF file, leading to arbitrary code execution within the context of the GIMP process. The vulnerability has a CVSS score of 7.8 and was publicly disclosed on July 29, 2026. GIMP has released an update that corrects this issue.
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 data. The attack requires user interaction, such as opening a malicious TIF file, but no other privileges are needed.
Mitigation Recommendations
GIMP has issued an official update that fixes this vulnerability. Users and administrators should apply the update promptly to remediate the risk. No additional mitigation steps are indicated by the vendor advisory.
