Synopsis

The remote Solaris system is missing a security patch from CPU jul2020.

Description

This Solaris system is missing necessary patches to address critical security updates :

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: Kernel). 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. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Solaris. Note: Please refer to <a href='https://support.oracle.com/rs?type=doc&id=2609642. 1'>My Oracle Support Note 2609642.1</a> for further information on how CVE-2018-12207 impacts Oracle Solaris. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H). (CVE-2018-12207)

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: Kernel). The supported version that is affected is 11. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise Oracle Solaris. 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. CVSS 3.1 Base Score 3.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N). (CVE-2019-5489)

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: Packaging Scripts). The supported version that is affected is 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. 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 5.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:N/I:N/A:H). (CVE-2020-14537)

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: libsuri). 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 read access to a subset of Oracle Solaris accessible data. CVSS 3.1 Base Score 3.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). (CVE-2020-14542)

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: Device Driver Utility). The supported version that is affected is 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. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Solaris accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Solaris. CVSS 3.1 Base Score 5.0 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:L). (CVE-2020-14545)

- Vulnerability in the Oracle Solaris product of Oracle Systems (component: Device Driver Utility). The supported version that is affected is 11.
