Published: 17 January 2018

Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: LDAP). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151; JRockit: R28.3.16. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Java SE Embedded, JRockit accessible data. Note: This vulnerability 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 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).

From the Ubuntu security team

It was discovered that the LDAP implementation in OpenJDK did not properly encode login names. A remote attacker could possibly use this to expose sensitive information.
