CVE-2018-3136: Low severity Oracle JDK vulnerability
It was discovered that the Security component of OpenJDK could incorrectly use unsigned manifest attribute entries when only properly signed entries were meant to be used. This could lead to bypass of protections provided by Jar signing. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
Other sources
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 6u201, 7u191, 8u182 and 11; Java SE Embedded: 8u181. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g. code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g. code installed by an administrator). CVSS 3.0 Base Score 3.4 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:L/A:N).
