Description OSIDB Bzimport 2026-07-06 18:55:05 UTC 
Integer overflow in GIMP's PSD parser. In read_RLE_channel() in psd-load.c, the allocation for rle_pack_len uses g_malloc (lyr_chn->rows * 4) with unchecked arithmetic. A crafted PSD can overflow the allocation size calculation and desynchronize it from the subsequent per-row writes, causing heap memory corruption.

- Function: read_RLE_channel()
- File: plug-ins/file-psd/psd-load.c:1843-1865
