ZDI-26-214: 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-2026-2049.
AI Analysis
Technical Summary
CVE-2026-2049 is a heap-based buffer overflow vulnerability in GIMP's HDR file parser. The flaw occurs due to insufficient validation of the length of user-supplied data before copying it into a heap buffer, allowing an attacker to execute arbitrary code in the context of the current process. Exploitation requires user interaction, such as opening a crafted HDR file. 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 released an update to fix this vulnerability as documented in their issue tracker.
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. The vulnerability requires user interaction but does not require elevated privileges or complex attack conditions.
Mitigation Recommendations
GIMP has issued an official update that corrects this vulnerability. Users should apply the update promptly to mitigate the risk. Since the vendor has provided a fix, no additional mitigation steps are necessary beyond applying the official patch.
