Sergey Poznyakoff reports:

This stable release fixes several potential vulnerabilities

CVE-2015-1197: cpio, when using the --no-absolute-filenames option, allows 
local users to write to arbitrary files via a symlink attack on a file in an 
archive.

CVE-2016-2037: The cpio_safer_name_suffix function in util.c allows remote 
attackers to cause a denial of service (out-of-bounds write) via a crafted 
cpio file.

CVE-2019-14866: Improper input validation when writing tar header fields leads
to unexpected tar generation.
