  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: SMB Server). The supported version
    that is affected is 11. Easily exploitable vulnerability
    allows low privileged attacker with logon to the
    infrastructure where Oracle Solaris executes to
    compromise Oracle Solaris. Successful attacks of this
    vulnerability can result in unauthorized update, insert
    or delete access to some of Oracle Solaris accessible
    data. (CVE-2019-9579)

  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: Kernel). Supported versions that are
    affected are 10 and 11. Easily exploitable vulnerability
    allows low 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.
    Successful attacks of this vulnerability can result in
    unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of Oracle Solaris.
