CVE-2018-5407: Infoleak

First published: Fri Nov 02 2018(Updated: )

A flaw was found in microprocessor execution engine sharing on SMT (e.g. Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process, can extract certain secret information. The reporter is able to steal an OpenSSL (&lt;= 1.1.0h) P-384 private key from a TLS server using this new side-channel vector. It is a local attack in the sense that the malicious process must be running on the same physical core as the victim (an openSSL-powered TLS server in this case). But in general any application which branches on a secret value may be affected. References: <a href="https://seclists.org/oss-sec/2018/q4/123">https://seclists.org/oss-sec/2018/q4/123</a>
