A flaw was found in the file-ico plugin in GIMP. (CVE-2026-82328)
Description
A vulnerability in the file-ico plugin of GIMP allows improper validation of the palette count parameter when processing specially crafted ICO image files. This leads to a heap out-of-bounds read, which can cause the application to crash, resulting in denial of service or limited disclosure of heap memory contents. The issue affects multiple specific versions of GIMP. The CVSS score is 6.1, indicating a medium severity level.

Technical Analysis
The file-ico plugin in GIMP improperly validates the used_clrs (palette count) parameter when handling specially crafted ICO image files. This incorrect validation causes improper memory bounds checking, resulting in a heap out-of-bounds read. The flaw can lead to an application crash causing denial of service or limited information disclosure of heap memory contents. The vulnerability affects numerous specific GIMP versions as listed, with a CVSS 3.1 score of 6.1 (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H). There is no indication of known exploits in the wild or vendor-provided patches in the provided data.
Potential Impact
Exploitation of this vulnerability can cause GIMP to crash, resulting in denial of service. Additionally, it may lead to limited disclosure of heap memory contents, which could potentially expose sensitive information. The attack vector requires local access with user interaction (UI required), and the impact on confidentiality is limited, with no integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, avoid opening untrusted ICO image files with GIMP to reduce risk.
