CVE-2018-0497

MEDIUM

ARM mbed TLS <2.12.0, <2.7.5, <2.1.14 - Info Disclosure

Title source: llm
STIX 2.1

Description

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.
