What's new in Sudo 1.7.2?
* A new #includedir directive is available in sudoers. This can be
used to implement an /etc/sudo.d directory. Files in an includedir
are not edited by visudo unless they contain a syntax error.
* The -g option did not work properly when only setting the group
(and not the user). Also, in -l mode the wrong user was displayed
for sudoers entries where only the group was allowed to be set.
* Fixed a problem with the alias checking in visudo which
could prevent visudo from exiting.
* Sudo will now correctly parse the shell-style /etc/environment
file format used by pam_env on Linux.
* When doing password and group database lookups, sudo will only
cache an entry by name or by id, depending on how the entry was
looked up. Previously, sudo would cache by both name and id
from a single lookup, but this breaks sites that have multiple
password or group database names that map to the same uid or
gid.
* User and group names in sudoers may now be enclosed in double
quotes to avoid having to escape special characters.
* BSM audit fixes when changing to a non-root uid.
* Experimental non-Unix group support. Currently only works with
Quest Authorization Services and allows Active Directory groups
fixes for Minix-3.
* For Netscape/Mozilla-derived LDAP SDKs the certificate and key
paths may be specified as a directory or a file. However, version
5.0 of the SDK only appears to support using a directory (despite
documentation to the contrary). If SSL client initialization
fails and the certificate or key paths look like they could be
default file name, strip off the last path element and try again.
* A setenv() compatibility fix for Linux systems, where a NULL
value is treated the same as an empty string and the variable
name is checked against the NULL pointer.
What's new in Sudo 1.7.1?
* A new Defaults option "pwfeedback" will cause sudo to provide visual
feedback when the user is entering a password.
* A new Defaults option "fast_glob" will cause sudo to use the fnmatch()
function for file name globbing instead of glob(). When this option
is enabled, sudo will not check the file system when expanding wildcards.
This is faster but a side effect is that relative paths with wildcard
will no longer work.
* New BSM audit support for systems that support it such as FreeBSD
and Mac OS X.
* The file name specified with the #include directive may now include
a %h escape which is expanded to the short form of hostname.
* The -k flag may now be specified along with a command, causing the
user's timestamp file to be ignored.
* New support for Tivoli-based LDAP START_TLS, present in AIX.
* New support for /etc/netsvc.conf on AIX.
* The unused alias checks in visudo now handle the case of an alias
referring to another alias.
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.
* A new Defaults option "umask_override" will cause sudo to set the
umask specified in sudoers even if it is more permissive than the
invoking user's umask.
