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(64)?/mailman/cgi-bin/.*
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
55 allow you to manipulate the policy and run mailman_cgi with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69
70 setsebool -P allow_kerberos 1
71
72
73
74 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76
77 setsebool -P allow_ptrace 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83
84 setsebool -P allow_ypbind 1
85
86
87
88 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91
92 setsebool -P domain_kernel_load_modules 1
93
94
95
96 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98
99 setsebool -P fips_mode 1
100
101
102
103 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105
106 setsebool -P global_ssp 1
107
108
109
110 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112
113 setsebool -P nscd_use_shm 1
114
115
116
118 The SELinux process type mailman_cgi_t can manage files labeled with
119 the following file types. The paths listed are the default paths for
120 these file types. Note the processes UID still need to have DAC per‐
121 missions.

173 SELinux requires files to have an extended attribute to define the file
174 type.
175
176 You can see the context of a file using the -Z option to ls
177
178 Policy governs the access confined processes have to these files.
179 SELinux mailman_cgi policy is very flexible allowing users to setup
180 their mailman_cgi processes in as secure a method as possible.
181
182 STANDARD FILE CONTEXT
183
184 SELinux defines the file context types for the mailman_cgi, if you
185 wanted to store files with these types in a diffent paths, you need to
186 execute the semanage command to sepecify alternate labeling and then
187 use restorecon to put the labels on disk.
188
189 semanage fcontext -a -t mailman_cgi_tmp_t '/srv/mymailman_cgi_con‐
190 tent(/.*)?'
191 restorecon -R -v /srv/mymailman_cgi_content
192
193 Note: SELinux often uses regular expressions to specify labels that
194 match multiple files.
195
196 The following file types are defined for mailman_cgi:
197
198
199
200 mailman_cgi_exec_t
201
202 - Set files with the mailman_cgi_exec_t type, if you want to transition
203 an executable to the mailman_cgi_t domain.
204
205
206
207 mailman_cgi_tmp_t
208
209 - Set files with the mailman_cgi_tmp_t type, if you want to store mail‐
210 man cgi temporary files in the /tmp directories.
211
212
213
214 Note: File context can be temporarily modified with the chcon command.
215 If you want to permanently change the file context you need to use the
216 semanage fcontext command. This will modify the SELinux labeling data‐
217 base. You will need to use restorecon to apply the labels.
218
219
221 semanage fcontext can also be used to manipulate default file context
222 mappings.
223
224 semanage permissive can also be used to manipulate whether or not a
225 process type is permissive.
226
227 semanage module can also be used to enable/disable/install/remove pol‐
228 icy modules.
229
230 semanage boolean can also be used to manipulate the booleans
231
232
233 system-config-selinux is a GUI tool available to customize SELinux pol‐
234 icy settings.
