| Titre | libvips 8.19.0(7fab325d2) Improper Validation of Array Index |
|---|
| Description | In `libvips/conversion/bandrank.c`, function `vips_bandrank_build()` accepts user-controlled `index` but does not validate it against the runtime input count (`bandary->n`) when explicitly set. `vips_bandrank_buffer()` later uses `sort[bandrank->index]` directly, causing out-of-bounds access when `--index` exceeds the number of input images. The bug is reachable from normal `vips bandrank` CLI usage and is reproducible with ASAN as `heap-buffer-overflow`. |
