6 mailman_cgi_selinux - Security Enhanced Linux Policy for the mail‐
7 man_cgi processes
8
10 Security-Enhanced Linux secures the mailman_cgi processes via flexible
11 mandatory access control.
12 The mailman_cgi processes execute with the mailman_cgi_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep mailman_cgi_t
20
24 The mailman_cgi_t SELinux type can be entered via the mail‐
25 man_cgi_exec_t file type.
26 The default entrypoint paths for the mailman_cgi_t domain are the fol‐
28 lowing:
29 /usr/lib/mailman.*/cgi-bin/.*, /usr/lib/cgi-bin/mailman.*/.*
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 mailman_cgi policy is very flexible allowing users to setup their mail‐
40 man_cgi processes in as secure a method as possible.
41 The following process types are defined for mailman_cgi:
43 mailman_cgi_t
45 Note: semanage permissive -a mailman_cgi_t can be used to make the
47 process type mailman_cgi_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. mail‐
54 man_cgi policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run mailman_cgi with the tight‐
56 est access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type mailman_cgi_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101 fusefs_t
103 /var/run/user/[^/]*/gvfs
105 mailman_archive_t
107 /var/lib/mailman.*/archives(/.*)?
109 mailman_cgi_tmp_t
111 mailman_data_t
114 /etc/mailman.*
116 /var/lib/mailman(/.*)?
117 /var/spool/mailman.*
118 mailman_lock_t
120 /var/lock/mailman.*
122 /var/lock/subsys/mailman.*
123 mailman_log_t
125 /var/log/mailman.*
127
130 SELinux requires files to have an extended attribute to define the file
131 type.
132 You can see the context of a file using the -Z option to ls
134 Policy governs the access confined processes have to these files.
136 SELinux mailman_cgi policy is very flexible allowing users to setup
137 their mailman_cgi processes in as secure a method as possible.
138 STANDARD FILE CONTEXT
140 SELinux defines the file context types for the mailman_cgi, if you
142 wanted to store files with these types in a diffent paths, you need to
143 execute the semanage command to sepecify alternate labeling and then
144 use restorecon to put the labels on disk.
145 semanage fcontext -a -t mailman_cgi_tmp_t '/srv/mymailman_cgi_con‐
147 tent(/.*)?'
148 restorecon -R -v /srv/mymailman_cgi_content
149 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152 The following file types are defined for mailman_cgi:
154 mailman_cgi_exec_t
158 - Set files with the mailman_cgi_exec_t type, if you want to transition
160 an executable to the mailman_cgi_t domain.
161 Paths:
164 /usr/lib/mailman.*/cgi-bin/.*, /usr/lib/cgi-bin/mailman.*/.*
165 mailman_cgi_tmp_t
168 - Set files with the mailman_cgi_tmp_t type, if you want to store mail‐
170 man cgi temporary files in the /tmp directories.
171 Note: File context can be temporarily modified with the chcon command.
175 If you want to permanently change the file context you need to use the
176 semanage fcontext command. This will modify the SELinux labeling data‐
177 base. You will need to use restorecon to apply the labels.
178
181 semanage fcontext can also be used to manipulate default file context
182 mappings.
183 semanage permissive can also be used to manipulate whether or not a
185 process type is permissive.
186 semanage module can also be used to enable/disable/install/remove pol‐
188 icy modules.
189 semanage boolean can also be used to manipulate the booleans
191 system-config-selinux is a GUI tool available to customize SELinux pol‐
194 icy settings.
