This update for util-linux fixes a number of bugs and two security issues.

The following security bugs were fixed:

  • CVE-2016-5011: Infinite loop DoS in libblkid while parsing DOS partition (bsc#988361)
  • CVE-2017-2616: In su with PAM support it was possible for local users to send SIGKILL to selected other processes with root privileges (bsc#1023041).

The following non-security bugs were fixed:

  • bsc#1008965: Ensure that the option "users,exec,dev,suid" work as expected on NFS mounts
  • bsc#1012504: Fix regressions in safe loop re-use patch set for libmount

  • bsc#947494: mount -a would fail to recognize btrfs already mounted, address loop re-use in libmount
  • bsc#966891: Conflict in meaning of losetup -L. This switch in SLE12 SP1 and SP2 continues to carry the meaning of --logical-blocksize instead of upstream --nooverlap
  • bsc#978993: cfdisk would mangle some text output
  • bsc#982331: libmount: ignore redundant slashes
  • bsc#983164: mount uid= and gid= would reject valid non UID/GID values
  • bsc#987176: When mounting a subfolder of a CIFS share, mount -a would show the mount as busy
  • bsc#1019332: lscpu: Implement WSL detection and work around crash
