TITLE

Apple macOS of EFI In the component FileVault 2 Vulnerability in obtaining encrypted passwords

DESCRIPTION

An issue was discovered in certain Apple products. macOS before 10.12.4 is affected. The issue involves mishandling of DMA in the "EFI" component. It allows physically proximate attackers to discover the FileVault 2 encryption password via a crafted Thunderbolt adapter. Apple macOS is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, obtain sensitive information, cause a denial-of-service condition, or bypass security restrictions and perform unauthorized actions. This may aid in further attacks. EFI is one of the firmware upgrade interface components. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2017-03-27-3 macOS Sierra 10.12.4, Security Update 2017-001 El Capitan, and Security Update 2017-001 Yosemite macOS Sierra 10.12.4, Security Update 2017-001 El Capitan, and Security Update 2017-001 Yosemite are now available and address the following: apache Available for: macOS Sierra 10.12.3 Impact: A remote attacker may be able to cause a denial of service Description: Multiple issues existed in Apache before 2.4.25.
