Ubuntu Security Notice USN-4496-1
September 15, 2020

Apache XML-RPC vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS


Apache XML-RPC could be made to execute arbitrary code if it received
specially crafted data by a malicious XML-RPC server.

Software Description:
- libxmlrpc3-java: XML-RPC implementation in Java


It was discovered that Apache XML-RPC (aka ws-xmlrpc) does not properly
deserialize untrusted data. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2019-17570)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
  libxmlrpc3-client-java          3.1.3-9+deb10u1build0.18.04.1
  libxmlrpc3-common-java          3.1.3-9+deb10u1build0.18.04.1
  libxmlrpc3-server-java          3.1.3-9+deb10u1build0.18.04.1

Ubuntu 16.04 LTS:
  libxmlrpc3-client-java          3.1.3-7+deb8u1build0.16.04.1
  libxmlrpc3-common-java          3.1.3-7+deb8u1build0.16.04.1
  libxmlrpc3-server-java          3.1.3-7+deb8u1build0.16.04.1

In general, a standard system update will make all the necessary changes.
