A empresa Intel divulgou informa\u00e7\u00f5es sobre uma nova classe de vulnerabilidades em seus processadores \u2014 MDS (Microarchitectural Data Sampling). Assim como nos ataques da classe Spectre, os novos problemas podem levar ao vazamento de dados confidenciais do sistema operacional, m\u00e1quinas virtuais e processos de terceiros. Acredita-se que as falhas foram inicialmente identificadas por funcion\u00e1rios e parceiros da Intel durante uma auditoria interna. Em junho e agosto de 2018, informa\u00e7\u00f5es sobre os problemas na Intel tamb\u00e9m foram compartilhadas por pesquisadores independentes, ap\u00f3s o que um trabalho conjunto com fabricantes e desenvolvedores de sistemas operacionais foi realizado por quase um ano para identificar poss\u00edveis vetores de ataque e entregar corre\u00e7\u00f5es. Os processadores AMD e ARM n\u00e3o s\u00e3o afetados pela quest\u00e3o.\n<\/p>\n

\nVulnerabilidades identificadas:<\/p>\n

CVE-2018-12126 \u2014 MSBDS (Microarchitectural Store Buffer Data Sampling), recupera\u00e7\u00e3o do conte\u00fado dos buffers de armazenamento. Usado no ataque Fallout. A gravidade foi classificada em 6.5 pontos (CVSS);<\/p>\n

CVE-2018-12127 \u2014 MLPDS (Microarchitectural Load Port Data Sampling), recupera\u00e7\u00e3o do conte\u00fado dos portos de carga. Usado no ataque RIDL. CVSS 6.5;<\/p>\n

CVE-2018-12130 \u2014 MFBDS (Microarchitectural Fill Buffer Data Sampling), recupera\u00e7\u00e3o do conte\u00fado dos buffers de preenchimento. Usado nos ataques ZombieLoad e RIDL. CVSS 6.5;<\/p>\n

CVE-2019-11091 \u2014 MDSUM (Microarchitectural Data Sampling Uncacheable Memory), recupera\u00e7\u00e3o do conte\u00fado da mem\u00f3ria n\u00e3o cache\u00e1vel. Usado no ataque RIDL. CVSS 3.8. <\/p>\n<\/blockquote>\n
