Description OSIDB Bzimport 2026-07-06 18:58:02 UTC 
Stack overflow via VLAs in GIMP's TIM loader. In load_image() in file-tim.c, file-controlled width, height, and clut_size values are used directly in several variable-length array declarations on the stack across multiple decode paths. A crafted TIM file can therefore force oversized stack allocations and memory corruption.

- Function: load_image()
- File: plug-ins/common/file-tim.c
