Summary
A vulnerability in GIMP's parsing of XWD files allows remote code execution via an out-of-bounds write. Exploitation requires user interaction, such as opening a malicious file or visiting a crafted webpage.
Risk Assessment
The organization risks compromise of user workstations if a malicious XWD file is opened. An attacker can execute arbitrary code in the context of the current process, potentially leading to data theft or privilege escalation.
Recommendation
Update GIMP to the latest patched version immediately. Until then, avoid opening XWD files from untrusted sources.

- CVE-2017-17784High
In GIMP 2.8.22, there is a heap-based buffer over-read in load_image in plug-ins/common/file-gbr.c, related to mishandling of UTF-8 data.
- CVE-2016-4994High
A use-after-free vulnerability in the xcf_load_image function in xcf-load.c in GIMP allows remote attackers to cause a denial of service (program crash) or possibly execute arbitrary code via a crafted XCF file.
- CVE-2026-82343Medium
The file-psd plugin in GIMP contains a flaw where the channel-count parameter is not properly validated when processing specially crafted PSD files. This leads to improper memory bounds checking, resulting in a heap out-of-bounds read and a stack out-of-bounds access. This can cause an application crash, leading to denial of service or limited information disclosure of memory contents.
- CVE-2026-82330Medium
A flaw was found in the file-pvr plugin in GIMP. When processing a specially crafted PVR image file, the VQ (compressed) decoder does not properly perform memory bounds checking. This missing validation results in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.
- CVE-2026-82328Medium
A flaw was found in the file-ico plugin in GIMP. When processing a specially crafted ICO image file, the plugin does not properly validate the used_clrs (palette count) parameter. This incorrect validation leads to improper memory bounds checking, resulting in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.
- CVE-2026-82324Medium
A flaw was found in the file-iff (IFF/ILBM) plugin in GIMP. When processing a specially crafted IFF/ILBM image file, the plugin does not properly validate the HAM row size and improperly handles cases where the number of color planes (nPlanes) is zero. This causes a row size mismatch that bypasses memory bounds checking, resulting in heap out-of-bounds reads. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.
Original NVD description (English source)
GIMP XWD File Parsing Out-Of-Bounds Write 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 specific flaw exists within the parsing of XWD files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28591.
