CVE-2020-14779: Medium severity ibm cloud pak for automation vulnerability
An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
Other sources
It was discovered that the implementation of the Proxy class in the Serialization component of OpenJDK could trigger an out-of-memory condition when deserializing Proxy class objects with many interfaces. A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.
The patch for this issue adds a new system property jdk.serialProxyInterfaceLimit that can be used to reduce the limit for Proxy interfaces from the default of 65535 and hence better protect against excessive memory usage.
