  - Vulnerability in the Oracle Solaris product of Oracle
    Systems (component: Whodo). Supported versions that are
    affected are 10 and 11. Difficult to exploit
    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
    and while the vulnerability is in Oracle Solaris,
    attacks may significantly impact additional products.
    Successful attacks of this vulnerability can result in
    unauthorized read access to a subset of Oracle Solaris
    accessible data. (CVE-2020-2771)"
