CVE-2026-42170

Gimp: gimp dds plug-in heap-based buffer overflow via bpp mismatch in load_layer() (ddsread.c)

Published Aug 8, 2026 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution.

Remediation

Vendor Workaround

Users should avoid opening untrusted DirectDraw Surface (DDS) image files with GIMP. As a general security practice, only process files from trusted sources. If GIMP is not essential, consider removing the `gimp` package to eliminate this attack vector.
