CVE-2018-0497 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 mbedtls to version 2.2.1-2ubuntu0.3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mbedtls package and not the mbedtls package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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.
