The remote OracleVM system is missing necessary patches to address critical security updates :
clean up empty file if cp is failed [Orabug 15973168]
pure rebuild to bring back support for acl_extended_file_nofollow on x86_64
su: deny killing other processes with root privileges (CVE-2017-2616)
fix the functionality of ‘sort -h -k …’ in multi-byte locales (#1357979)
use correct path to grep(1) in colorls.sh (#1376892)
make colorls.sh compatible with ksh (#1321643)
sed should actually be /bin/sed (related #1222140)
colorls.sh,colorls.csh - call utilities with complete path (#1222140)
mkdir, mkfifo, mknod - respect default umask/acls when COREUTILS_CHILD_DEFAULT_ACLS envvar is set (to match rhel 7 behaviour,
ls: improve efficiency on filesystems without support for ACLs, xattrs or SELinux (#1248141)
su: suppress PAM info messages for -c or non-login sessions (#1267588)
tail, stat: recognize several new filesystems - up2date by Jan 1st 2016 (#1280333)
du: improve du error message of coreutils commands in a chrooted environment (patch by Boris Ranto) (#1086916)
