1) Information disclosure

EUVDB-ID: #VU14174

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-0497

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.
