CVE-2025-46712

Erlang/OTP is a set of libraries for the Erlang programming language. In versions prior to OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25), Erlang/OTP SSH fails to enforce strict KEX handshake hardening measures by allowing optional messages to be exchanged. This allows a Man-in-the-Middle attacker to inject these messages in a connection during the handshake. This issue has been patched in versions OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25).

Summary		(es) Erlang/OTP es un conjunto de librerías para el lenguaje de programación Erlang. En versiones anteriores a OTP-27.3.4 (para OTP-27), OTP-26.2.5.12 (para OTP-26) y OTP-25.3.2.21 (para OTP-25), Erlang/OTP SSH no aplica medidas estrictas de reforzamiento del protocolo de enlace KEX al permitir el intercambio de mensajes opcionales. Esto permite que un atacante intermediario inyecte estos mensajes en una conexión durante el protocolo de enlace. Este problema se ha corregido en las versiones OTP-27.3.4 (para OTP-27), OTP-26.2.5.12 (para OTP-26) y OTP-25.3.2.21 (para OTP-25).
