---------------------------------
Product: libxmlrpc3-java
Publisher: Debian
Operating System: Debian GNU/Linux

- --------------------------BEGIN INCLUDED TEXT--------------------
Package : libxmlrpc3-java
CVE ID : CVE-2019-17570
Debian Bug : 949089
Guillaume Teissier reported that the XMLRPC client in libxmlrpc3-java,
an XML-RPC implementation in Java, does perform deserialization of the
server-side exception serialized in the faultCause attribute of XMLRPC
error response messages. A malicious XMLRPC server can take advantage of
this flaw to execute arbitrary code with the privileges of an
application using the Apache XMLRPC client library.
Note that a client that expects to get server-side exceptions need to
set explicitly the enabledForExceptions property.
For the oldstable distribution (stretch), this problem has been fixed
in version 3.1.3-8+deb9u1.
For the stable distribution (buster), this problem has been fixed in
version 3.1.3-9+deb10u1.
We recommend that you upgrade your libxmlrpc3-java packages.
