    Fix heap-buffer-overflow in Swift tree-sitter scanner

    frostbyte_neo 发布于 2026-03-12 13:03:39 +00:00

    The Swift external scanner called calloc(0, sizeof(ScannerState)) which
    returns a 0-or-1-byte allocation per the C standard. The scanner then
    writes a uint32_t (4 bytes) to this region via state->ongoing_raw_str_hash_count,
    causing a heap-buffer-overflow detected by AddressSanitizer.

    Fix: calloc(0, ...) → calloc(1, ...).
