Summary
A heap-based buffer overflow vulnerability exists in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD file, an integer overflow occurs during multiplication of values from an embedded JPEG header, leading to an undersized heap allocation and a heap-based buffer overflow during image decoding.
Risk Assessment
Opening a malicious PSD file in GIMP can lead to an application crash or arbitrary code execution in the context of the GIMP process. This can result in compromise of the user's system.
Recommendation
Update GIMP to a version containing the file-psd plugin fix. Avoid opening PSD files from untrusted sources until patched.

- CVE-2017-17785High
In GIMP 2.8.22, there is a heap-based buffer overflow in the fli_read_brun function in plug-ins/file-fli/fli.c.
- 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-2026-97185High
In GIMP, when processing a specially crafted GIMPressionist preset file, the plug-in does not properly validate vector indices before writing into fixed-size arrays. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to load a malicious preset file, potentially causing a crash or enabling arbitrary code execution.
- CVE-2026-96546Low
GIMP's uncompressed DDS image loader has a one-byte out-of-bounds heap read flaw. After processing the final pixel, the file-dds plug-in performs an unconditional one-byte look-ahead, which may cause a crash if the byte is inaccessible.
- CVE-2026-96545Medium
An out-of-bounds heap read flaw exists in GIMP's TIM image loader. When a user opens a crafted 4bpp TIM image that causes promotion to an RGBA layer, the file-tim plug-in allocates an undersized row buffer but processes it using the larger RGBA row size. This can copy adjacent heap contents into the decoded image and may crash the plug-in.
- CVE-2026-90947High
GIMP when processing a specially crafted lighting preset file does not properly validate the number of light sources in the Lighting Effects filter. This can lead to an out-of-bounds write, potentially causing a crash or enabling arbitrary code execution.
Original NVD description (English source)
A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.
