Description Philipp Hahn

New Debian util-linux 2.29.2-1+deb9u1 fixes:
This update addresses the following issue:
* bash-completion for umount allows local users to gain privileges by
  embedding shell commands in a mountpoint name, which is mishandled during a
  umount command (within Bash) by a different user, as demonstrated by
  logging in as root and entering umount followed by a tab character for
  autocompletion. (CVE-2018-7738)

CVE-2018-7738 util-linux: Shell command injection in unescaped bash-completed mount point names
