Prior to 14.0.0, v3, v5, and v6 accept external output buffers but do not reject out-of-range writes (small buf or large offset). This allows silent partial writes into caller-provided buffers. This vulnerability is fixed in 14.0.0."

Antes de la 14.0.0, v3, v5 y v6 aceptan búferes de salida externos pero no rechazan escrituras fuera de rango (búfer pequeño o desplazamiento grande). Esto permite escrituras parciales silenciosas en búferes proporcionados por el llamador. Esta vulnerabilidad está corregida en la 14.0.0."
