Descriptions

Class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD <= 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. The class is one of several implementations that an implementor using Apache MINA SSHD can choose for loading the host keys of an SSH server.

La clase org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider en Apache MINA SSHD anteriore a la versión 2.9.1 usa la deserialización de Java para cargar una java.security.PrivateKey serializada. La clase es una de varias implementaciones que un implementador que usa Apache MINA SSHD puede elegir para cargar las claves de host de un servidor SSH.

A flaw was found in Apache MINA SSHD, when using Java deserialization to load a serialized java.security.PrivateKey. An attacker could benefit from unsafe deserialization by inserting unsecured data that may affect the application or server.

Red Hat JBoss Enterprise Application Platform 7 is a platform for Java applications based on the WildFly application runtime.
