TTCSIRT-049.100617: TT-CSIRT Advisory – Apple Security Updates
Apple has released a supplemental security update to address vulnerabilities in macOS High Sierra 10.13:
a) A local attacker may gain access to an encrypted APFS volume – if a hint was set in Disk Utility when creating an APFS encrypted volume, the password was stored as the hint.
b) A malicious application can extract keychain passwords – a method existed for applications to bypass the keychain access prompt with a synthetic click.
