sudo 1.7.0

[willimm]

BRAND new version.

From WHATSNEW:

What's new in Sudo 1.7.0?

• Rewritten parser that converts sudoers into a set of data structures. This eliminates a number of ordering issues and makes it possible to apply sudoers Defaults entries before searching for the command. It also adds support for per-command Defaults specifications.

• Sudoers now supports a #include facility to allow the inclusion of other sudoers-format files.

• Sudo's -l (list) flag has been enhanced:

o applicable Defaults options are now listed o a command argument can be specified for testing whether a user

may run a specific command.

o a new -U flag can be used in conjunction with "sudo -l" to allow

root (or a user with "sudo ALL") list another user's privileges.

• A new -g flag has been added to allow the user to specify a primary group to run the command as. The sudoers syntax has been extended to include a group section in the Runas specification.

• A uid may now be used anywhere a username is valid.

• The "secure_path" run-time Defaults option has been restored.

• Password and group data is now cached for fast lookups.

• The file descriptor at which sudo starts closing all open files is now configurable via sudoers and, optionally, the command line.

• Visudo will now warn about aliases that are defined but not used.

• The -i and -s command line flags now take an optional command to be run via the shell. Previously, the argument was passed to the shell as a script to run.

• Improved LDAP support. SASL authentication may now be used in conjunction when connecting to an LDAP server. The krb5_ccname parameter in ldap.conf may be used to enable Kerberos.

• Support for /etc/nsswitch.conf. LDAP users may now use nsswitch.conf to specify the sudoers order. E.g.:

sudoers: ldap files

to check LDAP, then /etc/sudoers. The default is "files", even when LDAP support is compiled in. This differs from sudo 1.6 where LDAP was always consulted first.

• Support for /etc/environment on AIX and Linux. If sudo is run with the -i flag, the contents of /etc/environment are used to populate the new environment that is passed to the command being run.

• If no terminal is available or if the new -A flag is specified, sudo will use a helper program to read the password if one is configured. Typically, this is a graphical password prompter such as ssh-askpass.

• A new Defaults option, "mailfrom" that sets the value of the "From:" field in the warning/error mail. If unspecified, the login name of the invoking user is used.

• A new Defaults option, "env_file" that refers to a file containing environment variables to be set in the command being run.

• A new flag, -n, may be used to indicate that sudo should not prompt the user for a password and, instead, exit with an error if authentication is required.

• If sudo needs to prompt for a password and it is unable to disable echo (and no askpass program is defined), it will refuse to run unless the "visiblepw" Defaults option has been specified.

• Prior to version 1.7.0, hitting enter/return at the Password: prompt would exit sudo. In sudo 1.7.0 and beyond, this is treated as an empty password. To exit sudo, the user must press ^{C or} D at the prompt.

• visudo will now check the sudoers file owner and mode in -c (check) mode when the -s (strict) flag is specified.

If you don't want to upgrade to that version, you can use 1.6.9p19.
