None of these fixes are applicable to client-only installations, i.e., installations that do not have the Oracle Database Server installed. o 1 new security fix for Oracle Big Data Graph. This vulnerability is remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials. o 3 new security fixes for Oracle GoldenGate. All of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials. The English text form of this Risk Matrix can be found here." [1] "CVE-2018-3259 9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java VM. Successful attacks of this vulnerability can result in takeover of Java VM. CVE-2018-3299 8.2 AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:H Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Text. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Text, 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 Text as well as unauthorized update, insert or delete access to some of Oracle Text accessible data. CVE-2018-7489 2.3 AV:A/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:L Difficult to exploit vulnerability allows low privileged attacker having RHP User privilege with access to the physical communication segment attached to the hardware where the Rapid Home Provisioning executes to compromise Rapid Home Provisioning. 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 partial denial of service (partial DOS) of Rapid Home Provisioning. CVE-2016-6814 9.6 AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H Supported versions that are affected are 2.0, 2.1 and 2.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Spatial. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Spatial, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Spatial. CVE-2018-2913 10.0. AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H Vulnerability in the Oracle GoldenGate component of Oracle GoldenGate (subcomponent: Monitoring Manager). Supported versions that are affected are 12.1.2.1.0, 12.2.0.2.0 and 12.3.0.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle GoldenGate. While the vulnerability is in Oracle GoldenGate, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle GoldenGate. Note: For Linux and Windows platforms, the CVSS score is 9.0 with Access Complexity as High. For all other platforms, the cvss score is 10.0. CVE-2018-2912 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Supported versions that are affected are 12.1.2.1.0, 12.2.0.2.0 and 12.3.0.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle GoldenGate. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle GoldenGate. CVE-2018-2914 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Supported versions that are affected are 12.1.2.1.0, 12.2.0.2.0 and 12.3.0.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle GoldenGate. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle GoldenGate." [2] MITIGATION 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."
