CVE-2018-12436 (GCVE-0-2018-12436)

Vulnerability from cvelistv5 – Published: 2018-06-15 02:00 – Updated: 2024-09-17 00:51

Summary

wolfcrypt/src/ecc.c in wolfSSL before 3.15.1.patch allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.

Severity

No CVSS data available.
