How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream xstream package and not the xstream package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
