ZDI-26-454: GIMP PSD 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-2026-18301.
AI Analysis
Technical Summary
CVE-2026-18301 is an integer overflow vulnerability in the PSD file parser of GIMP. The vulnerability occurs due to insufficient validation of user-supplied data, which can cause an integer overflow prior to buffer allocation. This can be exploited by remote attackers who trick users into opening crafted malicious PSD files, resulting in arbitrary code execution within the context of the GIMP process. The vulnerability has a CVSS score of 7.8 and requires user interaction for exploitation. GIMP has released an update that fixes this issue.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code on affected GIMP installations with the privileges of the current user. This can lead to full compromise of the user's environment where GIMP is run. The attack requires user interaction (opening a malicious PSD file).
Mitigation Recommendations
GIMP has issued an official update that corrects this vulnerability. Users should apply the update provided by GIMP to remediate this issue. No other mitigation steps are indicated by the vendor advisory.
