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.
