ZDI-26-457: 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-2026-18304.
AI Analysis
Technical Summary
CVE-2026-18304 is an integer overflow vulnerability in GIMP's TIF file parser. The flaw occurs due to insufficient validation of user input, causing an integer overflow during buffer allocation. This can be exploited by remote attackers to execute arbitrary code within the context of the GIMP process. Exploitation requires user interaction, such as opening a crafted malicious TIF file. The vulnerability has a CVSS score of 7.8 (high severity). GIMP has issued an official patch to remediate 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 attack requires user interaction but does not require elevated privileges or complex attack vectors.
Mitigation Recommendations
An official patch has been released by GIMP to fix this vulnerability. Users and administrators should apply the update provided by GIMP to remediate the issue. Until patched, avoid opening untrusted TIF files from unknown or untrusted sources.
