  - Vulnerability in the Oracle Solaris product of Oracle
    Sun Systems Products Suite (component: Zones). The
    supported version that is affected is 11.4. 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 update, insert
    or delete access to some of Oracle Solaris accessible
    data and unauthorized ability to cause a partial denial
    of service (partial DOS) of Oracle Solaris.

    Sun Systems Products Suite (component: Gnuplot). The
    supported version that is affected is 11.4. 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 takeover of Oracle Solaris.
    (CVE-2019-2820)

  - Vulnerability in the Oracle Solaris product of Oracle
    Sun Systems Products Suite (component: Kernel). The
