Original NVD description (English source)
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Libraries). The supported version that is affected is 11.4. Difficult to exploit vulnerability allows unauthenticated 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. CVSS 3.1 Base Score 4.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H).
