CVE-2017-10109: Medium severity oracle java se 7 vulnerability
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.
Other sources
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: Serialization). Supported versions that are affected are Java SE: 6u151, 7u141 and 8u131; Java SE Embedded: 8u131; JRockit: R28.3.14. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
