CVE-2017-3511: High severity Oracle JDK vulnerability
A untrusted library search path flaw was found in the JCE (Java Cryptography Extension) component of OpenJDK, caused by a problem with the handling of paths to extension directories in the sun.misc.Launcher class. A local attacker could possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and therefore escalate their privileges.
Other sources
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JCE). Supported versions that are affected are Java SE: 7u131 and 8u121; Java SE Embedded: 8u121; JRockit: R28.3.13. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Java SE, Java SE Embedded, JRockit executes to compromise Java SE, Java SE Embedded, JRockit. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, JRockit, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover 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. CVSS 3.0 Base Score 7.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).
