Dirk Mueller 7c6c82c48c Accepting request 738914 from home:vitezslav_cizek:branches:Base:System
- Update to 1.8,28p1
  * The fix for Bug #869 caused "sudo -v" to prompt for a password
    when "verifypw" is set to "all" (the default) and all of the
    user's sudoers entries are marked with NOPASSWD.  Bug #901.

- Update to 1.8.28
 * Fixed CVE-2019-14287 (bsc#1153674),
   a bug where a sudo user may be able to
   run a command as root when the Runas specification explicitly
   disallows root access as long as the ALL keyword is listed first.
   * Sudo will now only set PAM_TTY to the empty string when no
   terminal is present on Solaris and Linux.  This workaround is
   only needed on those systems which may have PAM modules that
   misbehave when PAM_TTY is not set.
 * The mailerflags sudoers option now has a default value even if
   sendmail support was disabled at configure time.  Fixes a crash
   when the mailerpath sudoers option is set but mailerflags is not.
   Bug #878.
 * Sudo will now filter out last login messages on HP-UX unless it
   a shell is being run via "sudo -s" or "sudo -i".  Otherwise,
   when trusted mode is enabled, these messages will be displayed
   for each command.
 * Sudo has a new -B command line option that will ring the terminal
   bell when prompting for a password.
 * Sudo no longer refuses to prompt for a password when it cannot
   determine the user's terminal as long as it can open /dev/tty.
   This allows sudo to function on systems where /proc is unavailable,
   such as when running in a chroot environment.
 * The "env_editor" sudoers flag is now on by default.  This makes
   source builds more consistent with the packages generated by
