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
13 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
17 For example:
18
19 ps -eZ | grep mailman_cgi_t
20
21
22
24 The mailman_cgi_t SELinux type can be entered via the mail‐
25 man_cgi_exec_t file type.
26
27 The default entrypoint paths for the mailman_cgi_t domain are the fol‐
28 lowing:
29
30 /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
36 You can see the context of a process using the -Z option to ps
37
38 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
42 The following process types are defined for mailman_cgi:
43
44 mailman_cgi_t
45
46 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
51
53 SELinux policy is customizable based on least access required. mail‐
54 man_cgi policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run mailman_cgi with the tightest
56 access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type mailman_cgi_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

122 SELinux requires files to have an extended attribute to define the file
123 type.
124
125 You can see the context of a file using the -Z option to ls
126
127 Policy governs the access confined processes have to these files.
128 SELinux mailman_cgi policy is very flexible allowing users to setup
129 their mailman_cgi processes in as secure a method as possible.
130
131 STANDARD FILE CONTEXT
132
133 SELinux defines the file context types for the mailman_cgi, if you
134 wanted to store files with these types in a different paths, you need
135 to execute the semanage command to specify alternate labeling and then
136 use restorecon to put the labels on disk.
137
138 semanage fcontext -a -t mailman_cgi_exec_t '/srv/mailman_cgi/con‐
139 tent(/.*)?'
140 restorecon -R -v /srv/mymailman_cgi_content
141
142 Note: SELinux often uses regular expressions to specify labels that
143 match multiple files.
144
145 The following file types are defined for mailman_cgi:
146
147
148
149 mailman_cgi_exec_t
150
151 - Set files with the mailman_cgi_exec_t type, if you want to transition
152 an executable to the mailman_cgi_t domain.
153
154
155 Paths:
156 /usr/lib/mailman.*/cgi-bin/.*, /usr/lib/cgi-bin/mailman.*/.*
157
158
159 mailman_cgi_tmp_t
160
161 - Set files with the mailman_cgi_tmp_t type, if you want to store mail‐
162 man cgi temporary files in the /tmp directories.
163
164
165
166 Note: File context can be temporarily modified with the chcon command.
167 If you want to permanently change the file context you need to use the
168 semanage fcontext command. This will modify the SELinux labeling data‐
169 base. You will need to use restorecon to apply the labels.
170
171
173 semanage fcontext can also be used to manipulate default file context
174 mappings.
175
176 semanage permissive can also be used to manipulate whether or not a
177 process type is permissive.
178
179 semanage module can also be used to enable/disable/install/remove pol‐
180 icy modules.
181
182 semanage boolean can also be used to manipulate the booleans
183
184
185 system-config-selinux is a GUI tool available to customize SELinux pol‐
186 icy settings.
