Major changes between sudo 1.8.6 and 1.8.5p3:
* Sudo is now built with the -fstack-protector flag if the the
compiler supports it. Also, the -zrelro linker flag is used if
supported. The --disable-hardening configure option can be used
to build sudo without stack smashing protection.
* Sudo is now built as a Position Independent Executable (PIE)
if supported by the compiler and linker.
* If the user is a member of the "exempt" group in sudoers, they
will no longer be prompted for a password even if the -k flag
is specified with the command. This makes "sudo -k command"
consistent with the behavior one would get if the user ran "sudo
-k" immediately before running the command.
* The sudoers file may now be a symbolic link. Previously, sudo
would refuse to read sudoers unless it was a regular file.
* The sudoreplay command can now properly replay sessions where
no tty was present.
* The sudoers plugin now takes advantage of symbol visibility
controls when supported by the compiler or linker. As a result,
only a small number of symbols are exported which significantly
reduces the chances of a conflict with other shared objects.
* Improved support for the Tivoli Directory Server LDAP client
libraries. This includes support for using LDAP over SSL (ldaps)
as well as support for the BIND_TIMELIMIT, TLS_KEY and TLS_CIPHERS
ldap.conf options. A new ldap.conf option, TLS_KEYPW can be
used to specify a password to decrypt the key database.
* When constructing a time filter for use with LDAP sudoNotBefore
and sudoNotAfter attributes, the current time now includes tenths
of a second. This fixes a problem with timed entries on Active
Directory.
* If a user fails to authenticate and the command would be rejected
by sudoers, it is now logged with "command not allowed" instead
of "N incorrect password attempts". Likewise, the "mail_no_perms"
sudoers option now takes precedence over "mail_badpass".
* The sudo manuals are now formatted using the mdoc macros. Versions
using the legacy man macros are provided for systems that lack mdoc.
* New support for Solaris privilege sets. This makes it possible
to specify fine-grained privileges in the sudoers file on Solaris
10 and above. A Runas_Spec that contains no Runas_Lists can be
used to give a user the ability to run a command as themselves
but with an expanded privilege set.
* Fixed a problem with the reboot and shutdown commands on some
systems (such as HP-UX and BSD). On these systems, reboot sends
all processes (except itself) SIGTERM. When sudo received
SIGTERM, it would relay it to the reboot process, thus killing
reboot before it had a chance to actually reboot the system.
* Support for using the System Security Services Daemon (SSSD) as
a source of sudoers data.
* Slovenian translation for sudo and sudoers from translationproject.org.
* Visudo will now warn about unknown Defaults entries that are
per-host, per-user, per-runas or per-command.
* Fixed a race condition that could cause sudo to receive SIGTTOU
(and stop) when resuming a shell that was run via sudo when I/O
logging (and use_pty) is not enabled.
* Sending SIGTSTP directly to the sudo process will now suspend the
running command when I/O logging (and use_pty) is not enabled.
