CVE-2026-106065
MediumCVSS 6.3Summary
A heap-based buffer overflow was found in GIMP's PCX export plug-in. For images with extremely large width and height, buffer allocation uses overflowing 32-bit width * height arithmetic while subsequent GEGL operations use the full extent, after integer overflow in size calculation.
Risk Assessment
The risk is that processing specially crafted images could lead to program crashes or potential code execution, compromising system security.
Recommendation
Update GIMP to the latest patched version and avoid opening untrusted images with extreme dimensions.

See all- CVE-2017-17789High
In GIMP 2.8.22, there is a heap-based buffer overflow in read_channel_data in plug-ins/common/file-psp.c.
- CVE-2017-17787High
In GIMP 2.8.22, there is a heap-based buffer over-read in the read_creator_block handler in plug-ins/common/file-psp.c.
- CVE-2017-17786High
In GIMP 2.8.22, there is a heap-based buffer over-read in ReadImage in plug-ins/common/file-tga.c, related to an unexpected bits-per-pixel value for an RGBA image.
- 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-2026-106067Medium
A heap-based buffer overflow was found in GIMP’s Hot color filter plug-in. For very large images, a pixel buffer is allocated using overflowing 32-bit width * height (and related) arithmetic while the filter’s pixel access path uses the true image size, after integer overflow in the allocation size.
- CVE-2026-106066Medium
GIMP's raw data export plug-in contains a heap-based buffer overflow. When exporting very large images, sizing based on overflowing width * height * bytes-per-pixel can allocate far less memory than GEGL reads or writes during export, leading to a buffer overflow.
- CVE-2026-106064Medium
A heap-based buffer overflow exists in GIMP's GIF export plug-in. Exporting an image with very large width and height can cause a 32-bit overflow when computing the pixel buffer size, leading to an integer overflow and a mismatch between allocation and actual write by GEGL.
- CVE-2026-106061Medium
A flaw was found in GIMP's X cursor (XMC) thumbnail loader. When generating a thumbnail for a crafted XMC file, a pixel buffer is allocated using a width * height size computed in 32-bit signed arithmetic, which can overflow and lead to an out-of-bounds read on the heap.
