Gimp: gimp: heap out-of-bounds read/write in psd thumbnail loader (load_resource_1033)

Published Oct 19, 2026 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail can cause a heap out-of-bounds read and write in the plug-in process, leading to a crash and potentially arbitrary code execution when the victim browses or opens the file.

Remediation

Vendor Workaround

Avoid opening or browsing untrusted PSD files in GIMP. If GIMP is unused, remove the gimp package.
