Security researchers have published on the Project Zero a new vulnerability called Spectre and Meltdown allowing a program to steal information from a memory of others programs. It affects Intel, AMD and ARM architectures.
According to the Intel security-center post dated May 1, 2017, there is a critical vulnerability on Intel processors which could allow an attacker to gain privilege (escalation of privilege) using AMT, ISM and SBT.
Can I disable Spectre and Meltdown mitigation features in Ubuntu 18.04LTS?
Does the Ghost Vulnerability require access (as in being a logged in user) to the effected OS in question? Can someone clarify the ‘remote attacker that is able to make an application call’? I only seem to find tests to run on the local system directly but not from a remote host.
