Name of the Vulnerable Software and Affected Versions mbed TLS versions prior to 2.12.0 mbed TLS versions prior to 2.7.5 mbed TLS versions prior to 2.1.14

Description The issue allows remote attackers to achieve partial plaintext recovery for a CBC based ciphersuite via a timing-based side-channel attack. This is due to an incorrect fix for a previous issue, which involved a wrong SHA-384 calculation.

Recommendations For versions prior to 2.12.0, update to version 2.12.0 or later. For versions prior to 2.7.5, update to version 2.7.5 or later. For versions prior to 2.1.14, update to version 2.1.14 or later.
