CVE-2018-12433 (GCVE-0-2018-12433)

Vulnerability from cvelistv5 – Published: 2018-06-15 02:00 – Updated: 2024-09-16 19:35 Disputed

Summary

cryptlib through 3.4.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. NOTE: the vendor does not include side-channel attacks within its threat model
