It was discovered that the implementation of the AsynchronousChannelGroupImpl class in the java.nio.channels package of the Libraries component of OpenJDK failed to properly perform access control checks. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the implementation of the ImageWatched class in the AWT component of OpenJDK failed to properly perform access control checks. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the implementation of the ActivationID class in the RMI component of OpenJDK failed to properly perform access control checks. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the implementation of the ServiceRegistry class in the ImageIO component of OpenJDK failed to properly perform access control checks. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the LambdaFormEditor class in the Libraries component of OpenJDK did not correctly perform bounds checks in the permuteArgumentsForm() function. An untrusted Java application or applet could use this flaw to corrupt JVM memory and cause it to crash or, possibly, execute arbitrary code, bypassing Java sandbox restrictions. The problem is triggered when using MethodHandle.permuteArguments().

It was discovered that the LDAPCertStore class in the Security component of OpenJDK followed LDAP referrals to arbitrary URLs. A specially-crafted LDAP referral URL could cause LDAPCertStore to communicate with non-LDAP servers.

Oracle Java SE 7u151 and 8u141 fixes an unspecified vulnerability in the JavaFX component (CVE-2017-10114). Upstream has CVSS scored this issue as: 8.3/CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H

A covert timing channel flaw was found in the DSA implementation in the JCE component of OpenJDK. A remote attacker able to make a Java application generate DSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel.

Note that the fix for this issue reverts the fix for CVE-2016-5548 (see bug 1413920) and uses different approach to implement blinding of the DSA operations.

A covert timing channel flaw was found in the ECDSA implementation in the JCE component of OpenJDK. A remote attacker able to make a Java application generate ECDSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel.

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Deployment). Supported versions that are affected are Java SE: 7u141 and 8u131. Difficult to exploit vulnerability allows physical access to compromise Java SE. While the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. Note: Applies to deployment of Java where the Java Auto Update is enabled. CVSS 3.0 Base Score 7.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).

It was discovered that the Security component of OpenJDK could fail to properly enforce restrictions (specified using the jdk.certpath.disabledAlgorithms security property) defined for processing of X.509 certificate chains. A remote attacker could possibly use this flaw to make Java accept certificate using one of the disabled algorithms.

Oracle Java SE 6u161, 7u151, and 8u141 fixes an unspecified vulnerability in the JAX-WS component (CVE-2017-10243). Upstream has CVSS scored this issue as: 6.5/CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L

A covert timing channel flaw was found in the PKCS#8 implementation in the JCE component of OpenJDK. A remote attacker able to make a Java application repeatedly compared PKCS#8 key against an attacker controlled value could possibly use this flaw to determine the key via a timing side channel.

It was discovered that the implementation of the CodeSource class in OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form. An untrusted Java application or applet could use this flaw to cause JVM to allocate an excessive amount of memory, bypassing certain Java sandbox restrictions.

It was discovered that the implementation of the BasicAttribute class in OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form. A specially-crafted serialized input stream could cause JVM to consume an excessive amount of memory.

Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by a flaw when configured for showing a listing of directory contents. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to obtain sensitive information.

A flaw was found in the DisabledAlgorithmConstraints class in the Security component of OpenJDK. A key size constrained could not have been checked correctly in certain cases, causing weak key to be accepted. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
