SCA: security update for com.thoughtworks.xstream:xstream (GHSA-rmr5-cpv2-vgjf)

high Tenable Cloud Security Plugin ID 418823

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - XStream is an open source java library to serialize objects to XML and back again. Versions prior to
 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or
 parallel execution of such a payload resulting in a denial of service only by manipulating the processed
 input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and
 throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible.
 Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for
 further details on a workaround if an upgrade is not possible. (CVE-2021-43859)
