Descriptions

ARM mbed TLS before 2.12.0, before 2.7.5, and before 2.1.14 allows remote attackers to achieve partial plaintext recovery (for a CBC based ciphersuite) via a timing-based side-channel attack. This vulnerability exists because of an incorrect fix (with a wrong SHA-384 calculation) for CVE-2013-0169.

ARM mbed TLS en versiones anteriores a la 2.12.0, en versiones anteriores a la 2.7.5 y en versiones anteriores a la 2.1.14 permite a los atacantes remotos lograr una recuperación parcial de texto plano (para un ciphersuite basado en CBC) mediante un ataque de canal lateral basado en tiempo. Esta vulnerabilidad existe debido a una solución incorrecta (con un cálculo SHA-384 incorrecto) para CVE-2013-0169.
