https://sourceware.org/bugzilla/show_bug.cgi?id=19563

            Bug ID: 19563
           Summary: Missing escaping of backslashes in addmntent
           Product: glibc
           Version: 2.24
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---
             Flags: security+

The encode_name macro, used by addmntent, did not escape backslashes, allowing
unprivileged users to create crafted /etc/mtab entries on some systems.
