ZDI-26-282: GIMP HDR File Parsing Heap-based Buffer 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-2026-2050.
AI Analysis
Technical Summary
CVE-2026-2050 is a heap-based buffer overflow vulnerability in the HDR file parser of GIMP. The flaw is due to insufficient validation of the length of user-supplied data before copying it into a heap buffer, which can be exploited by an attacker to execute arbitrary code within the context of the GIMP process. Exploitation requires user interaction, such as opening a crafted malicious HDR file. The vulnerability has a CVSS v3 base 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 to fix this vulnerability, as referenced in their merge request.
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, limiting automatic exploitation. The CVSS score of 7.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
An official fix is available from GIMP. Users and administrators should apply the update provided by GIMP to remediate this vulnerability. No additional mitigation steps are required beyond applying the vendor's patch.
