SCA: security update for com.thoughtworks.xstream:xstream (GHSA-6wf9-jmg9-vxcc)

medium Tenable Cloud Security Plugin ID 411668

Description

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

 - XStream is a simple library to serialize objects to XML and back again. In affected versions this
 vulnerability 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. No user is affected, who followed the recommendation to setup XStream's security
 framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a
 blacklist by default, since it cannot be secured for general purpose. (CVE-2021-39140)
