  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: Utility). Supported versions that
    are affected are 10 and 11. Easily exploitable
    vulnerability allows high privileged attacker with logon
    to the infrastructure where Oracle Solaris executes to
    compromise Oracle Solaris. Successful attacks require
    human interaction from a person other than the attacker
    and while the vulnerability is in Oracle Solaris,
    attacks may significantly impact additional products
    (scope change). Successful attacks of this vulnerability
    can result in takeover of Oracle Solaris. CVSS 3.1 Base
    Score 7.7 (Confidentiality, Integrity and Availability
