| タイトル | libvips 8.19.0(7fab325d2) Signed to Unsigned Conversion Error |
|---|
| 説明 | In `libvips/foreign/matrixload.c`, function `vips_foreign_load_matrix_file_is_a()`, the return value of `vips__get_bytes()` (signed, may be `-1`) is stored in `guint64 bytes`. On read error, `-1` is converted to a very large unsigned value, and `line[bytes] = '\0'` performs a stack underflow write. The bug is reachable from the `vips` CLI loader detection path and is reproducible with ASAN as `stack-buffer-overflow`. |
