Descriptions

ARM mbed TLS before 1.3.21 and 2.x before 2.1.9, if optional authentication is configured, allows remote attackers to bypass peer authentication via an X.509 certificate chain with many intermediates. NOTE: although mbed TLS was formerly known as PolarSSL, the releases shipped with the PolarSSL name are not affected.

ARM mbed TLS en versiones anteriores a la 1.3.21 y en versiones 2.x anteriores a la 2.1.9, si se configura la autenticación opcional, permite a los atacantes omitir la autenticación Peer mediante una cadena de certificados X.509 con muchos intermediarios. NOTA: aunque mbed TLS se conocía antes como PolarSSL, las versiones lanzadas con el nombre PolarSSL no están afectadas.
