1) Information disclosure (CVE-ID: CVE-2018-0497)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists in ARM mbed TLS due to incomplete fix for CVE-2013-0169 and improper calculation of the secure hash algorithm-384 (SHA-384) when using a cipher suite based on cipher block chaining (CBC). A remote attacker who is able to observe and manipulate network packets can conduct a timing-based side-channel attack and partially recover the plaintext content.
