"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has cpio packages installed that are affected by a
vulnerability:
- In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may
contain files with permissions the attacker did not have or in paths he did not have access to. Extracting
those archives from a high-privilege user without carefully reviewing them may lead to the compromise of
the system. (CVE-2019-14866)
