| Titolo | libvips 8.19.0(7fab325d2) NULL Pointer Dereference (CWE-476) |
|---|
| Descrizione | In `libvips/foreign/matrixload.c`, function `vips_foreign_load_matrix_header()`, the return value of `vips_sbuf_get_line_copy()` is not checked for `NULL` before passing it to `parse_matrix_header()`. `parse_matrix_header()` then calls `strchr(line, ...)`, causing a NULL dereference on empty `.mat` input. The issue is reachable from `vips matrixload` and reproducible with ASAN as `SEGV` (denial of service). |
