CVE-2018-0497

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.
