Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Windows DLL). Supported versions that are affected are Java SE: 7u181 and 8u172. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and 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 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. CVSS 3.0 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

An infinite loop issue was found in the vhostnet kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handlerx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhostnet kernel thread, resulting in a DoS scenario.
It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the sname field from the plain text part rather than encrypted part of the KDC reply. A man-in-the-middle attacker could possibly use this flaw to impersonate Kerberos services to Java applications acting as Kerberos clients.
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.

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).
The Siemens R3964 line discipline driver in drivers/tty/nr3964.c in the Linux kernel before 5.0.8 has multiple race conditions.
It was discovered that the CardImpl class in the Smart Card IO component of OpenJDK failed to properly update its state in the finalize() method. An untrusted Java application or applet could possibly use this flaw to gain unexpected access to a smart card, bypassing certain Java sandbox restrictions.
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

It was discovered that key store implementations in the Security component of OpenJDK did not use sufficient number of iterations when generating password-based encryption keys used to protect private keys in key stores. This made it easier to perform password guessing attacks to decrypt stored keys if an attacker could gain access to a key store.
Oracle Java SE 6u171, 7u161, 8u151, and 9.0.1 fixes an unspecified vulnerability in the Javadoc component (CVE-2017-10293). Upstream has CVSS scored this issue as: 6.1/CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

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.
A flaw was found in the Linux kernel vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).
