CVE-2018-0488

ARM mbed TLS, en versiones anteriores a la 1.3.22, a la 2.1.10 y a la 2.7.0, cuando se usan las extensiones truncadas HMAC y CBC, permite que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (corrupción de memoria dinámica o heap) mediante un paquete de aplicación manipulado en una sesión TLS o DTLS.

It was discovered that mbedtls has a bounds-check bypass through an integer overflow that can be used by an attacked to execute arbitrary code or cause a denial of service. It was discovered that mbedtls has a vulnerability where an attacker could execute arbitrary code or cause a denial of service via a crafted certificate chain that is mishandled during RSASSA-PSS signature verification within a TLS or DTLS session. Various other issues were also addressed.
