f634241110 Fix for Bug #888 2019-07-19 14:10:57 -06:00
Todd C. Miller
a7137a5225 If the command in sudoers does not exist on the file system, match by name. 
We still want to match the command even if it doesn't exist so that the
NOPASSWD flag on sudoers entries with non-existant paths works as expected.
Bug #888.

c49760e55d Simpler change to retry sudo_secure_file() as root as needed. 2019-07-14 19:37:33 -06:00

cecf69ff3c If we are unable to stat() sudoers as non-root, try again as root. 
By default, sudo relies soley on group permissions to read sudoers
to make it possible to store sudoers on NFS.  However, if /etc/sudoers
is not accessible to non-root uids for some reason, sudo will fail.
Bug #880.

Todd C. Miller
caceced2f5 Use $libexecdir in default settings used by the documentation. 
The web and pdf pages will substitute /usr/local/libexec for $noexec_file.
Also do substitution of variables using exec_prefix even if we don't use
them in the Makefile since the documentation may reference them.

9d8f374397 Add ssizeof macro that returns ssize_t. 
We can use this instead of casting the result of size_t to int.
Also change checks for snprintf() returning <=0 to <0.

81602ad086 sudoedit should be used for editing files instead of "sudo editor" 
That way the user's editor config files are used by the editor.

1fe9644f54 Move the section on HOME to be after the environment section. 
Also strongly discourage the disabling of env_reset.

2d8949198d Remove the Solaris last login question, add one about HOME. 
The PAM session is opened with PAM_SILENT so last login info is not printed.
It is dangerous to preserve HOME from the user's environment.

Also mark set_home and always_set_home as obsolete.

71fdb8e037 Remove .cat pages, there is no need for them in the modern world. 
Sudo only shipped .cat pages for Irix, which lacked nroff.
Irix is long dead and there are multiple open source nroff options.

958cf7e37f Don't describe env_editor as a security hole. 
Users that are able to edit sudoers can grant themselves permissions
so the fact that visudo runs the editor as root is not a security issue.

6fe2223298 Fix details of how EDITOR, VISUAL and SUDO_EDITOR are (or are not) preserved. 
The description in the editor option was incorrect and didn't mention env_keep.

a193f39c83 Modern visudo locks the actual sudoers file, not the sudoers.tmp file. 
Refer to sudoers.tmp as a temporary file, not a lock file.

29223d7f64 In tty_present(), check for /dev/tty if sudo was unable to get the tty name. 
For requiretty it is enough to check that /dev/tty is available.
If sudo can't get the tty from the kernel (missing /proc?) that is OK.
 2019-06-19 20:32:22 -06:00
Todd C. Miller
82920726fa Don't refuse to use the tty unless /dev/tty is unavailable. 
We don't care whether sudo was able to get the tty name from the kernel.
All that really matters is whether we are able to disable echo as needed.

Otherwise, if the -h option is specified sudo will print the local
host name instead of the host specified via -h.

07ed5b86f2 When using AIX auth, don't display the AIX password incorrect message. 
Avoids a "3004-300 You entered an invalid login name or password"
message in addition to sudo's own "Sorry, try again" message.
