* xstream: Arbitrary code execution via unsafe deserialization of com.sun.jndi.ldap.LdapBindingEnumeration (CVE-2021-39145)
* xstream: Arbitrary code execution via unsafe deserialization of javax.swing.UIDefaults$ProxyLazyValue (CVE-2021-39146)
* xstream: Arbitrary code execution via unsafe deserialization of com.sun.jndi.ldap.LdapSearchEnumeration (CVE-2021-39147)
* xstream: Arbitrary code execution via unsafe deserialization of com.sun.jndi.toolkit.dir.ContextEnumerator (CVE-2021-39148)
* xstream: Arbitrary code execution via unsafe deserialization of com.sun.corba.* (CVE-2021-39149)
* xstream: Server-side request forgery (SSRF) via unsafe deserialization of com.sun.xml.internal.ws.client.sei.* (CVE-2021-39150)
* xstream: Arbitrary code execution via unsafe deserialization of com.sun.jndi.ldap.LdapBindingEnumeration (CVE-2021-39151)
* xstream: Server-side request forgery (SSRF) via unsafe deserialization of jdk.nashorn.internal.runtime.Source$URLData (CVE-2021-39152)
* xstream: Arbitrary code execution via unsafe deserialization of Xalan xsltc.trax.TemplatesImpl (CVE-2021-39153)
* xstream: Arbitrary code execution via unsafe deserialization of javax.swing.UIDefaults$ProxyLazyValue (CVE-2021-39154)
* xstream: Infinite loop DoS via unsafe deserialization of sun.reflect.annotation.AnnotationInvocationHandler (CVE-2021-39140)
