Synopsis

The remote Solaris system is missing a security patch from CPU jan2019.

Description

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

- Vulnerability in the Oracle Solaris component of Oracle Sun Systems Products Suite (subcomponent: Kernel). The supported version that is affected is 11. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Solaris. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Solaris. (CVE-2019-2437)

- Vulnerability in the Oracle Solaris component of Oracle Sun Systems Products Suite (subcomponent: Kernel). 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. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Solaris accessible data. (CVE-2018-3646)

- Vulnerability in the Oracle Communications LSMS product of Oracle Communications Applications (component: Kernel). Supported versions that are affected are 13.0-13.3. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Communications LSMS executes to compromise Oracle Communications LSMS. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Communications LSMS accessible data. CVSS 3.1 Base Score 5.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). (CVE-2018-3639)

Solution

Install the jan2019 CPU from the Oracle support website.
