CVE-2019-2832
8.8 AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Easily exploitable vulnerability allows low privileged attacker with
logon to the infrastructure where the affected system executes to
compromise the affected system. While the vulnerability is in the
affected system, attacks may significantly impact additional
products. Successful attacks of this vulnerability can result in
takeover of the affected system.
Affects:
o Oracle Solaris 10
CVE-2019-2844
8.8 AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

logon to the infrastructure where the affected system executes to
compromise the affected system. While the vulnerability is in the
affected system, attacks may significantly impact additional
products. Successful attacks of this vulnerability can result in
takeover of the affected system.
Affects:
o Oracle Solaris 11.4
CVE-2019-5598
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Easily exploitable vulnerability allows unauthenticated attacker with
network access via ICMPv6 to compromise the affected system.
Successful attacks of this vulnerability can result in unauthorized
creation, deletion or modification access to critical data or all the
affected system's accessible data.
Affects:
o Oracle Solaris 11.4
CVE-2019-2838
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Easily exploitable vulnerability allows unauthenticated attacker with

CVE-2019-2804
7.3 AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
Easily exploitable vulnerability allows low privileged attacker with
logon to the infrastructure where the affected system executes to
compromise the affected system. Successful attacks require human
interaction from a person other than the attacker. Successful attacks
of this vulnerability can result in takeover of the affected system.
Affects:

3.9 AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L
Easily exploitable vulnerability allows low privileged attacker with
logon to the infrastructure where the affected system executes to
compromise the affected system. 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 the affected system's accessible data and
unauthorized ability to cause a partial denial of service (partial
DOS) of the affected system.

o Oracle Solaris 11.4" [1]
MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle strongly
recommends that customers apply CPU fixes as soon as possible. Until
you apply the CPU fixes, it may be possible to reduce the risk of
successful attack by blocking network protocols required by an
attack. For attacks that require certain privileges or access to
certain packages, removing the privileges or the ability to access
the packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may break
application functionality, so Oracle strongly recommends that
customers test changes on non-production systems. Neither approach
should be considered a long-term solution as neither corrects the
underlying problem." [1]
