CVE-2026-41907

uuid is for the creation of RFC9562 (formerly RFC4122) UUIDs. 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.

Summary		(es) uuid es para la creación de UUIDs RFC9562 (anteriormente RFC4122). 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.
