Severity: Critical

Issue Overview:

Unbounded memory allocation during deserialization in Container (AWT, 8189989)
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: AWT). Supported versions that are affected are Java SE: 6u181, 7u171, 8u162 and 10; Java SE Embedded: 8u161; JRockit: R28.3.17. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. (CVE-2018-2798 )

Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets.

(CVE-2018-2815 )

Unrestricted deserialization of data from JCEKS key stores (Security, 8189997)
Vulnerability in the Java SE, JRockit component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 6u181, 7u171, 8u162, 10 and JRockit: R28.3.17. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Java SE, JRockit executes to compromise Java SE, JRockit. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, JRockit, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. (CVE-2018-2794 )

(CVE-2018-2795 )

Unbounded memory allocation during deserialization in NamedNodeMapImpl (JAXP, 8189993)
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JAXP). Supported versions that are affected are Java SE: 7u171, 8u162 and 10; Java SE Embedded: 8u161; JRockit: R28.3.17. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. (CVE-2018-2799 )

RMI HTTP transport enabled by default (RMI, 8193833)
Vulnerability in the Java SE, JRockit component of Oracle Java SE (subcomponent: RMI). Supported versions that are affected are Java SE: 6u181, 7u171 and 8u162; JRockit: R28.3.17. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, JRockit. 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 Java SE, JRockit accessible data as well as unauthorized read access to a subset of Java SE, JRockit accessible data. Note: This vulnerability can only be exploited by supplying data to APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. (CVE-2018-2800 )

Incorrect handling of Reference clones can lead to sandbox bypass (Hotspot, 8192025)
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Hotspot). Supported versions that are affected are Java SE: 6u181, 7u171, 8u162 and 10; Java SE Embedded: 8u161. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded.
