6 mozilla_selinux - Security Enhanced Linux Policy for the mozilla pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mozilla processes via flexible
11 mandatory access control.
12 The mozilla processes execute with the mozilla_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep mozilla_t
20
24 The mozilla_t SELinux type can be entered via the mozilla_exec_t file
25 type.
26 The default entrypoint paths for the mozilla_t domain are the follow‐
28 ing:
29 /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*firefox[^/]*/firefox-
31 bin, /usr/lib/mozilla[^/]*/reg.+, /usr/lib/firefox[^/]*/mozilla-.*,
32 /usr/lib/mozilla[^/]*/mozilla-.*, /usr/bin/mozilla-[0-9].*,
33 /usr/lib/netscape/.+/communicator/communicator-smotif.real,
34 /usr/bin/mozilla-bin-[0-9].*, /usr/bin/mozilla, /usr/bin/epiphany,
35 /usr/bin/netscape, /usr/bin/epiphany-bin, /usr/lib/galeon/galeon,
36 /usr/bin/mozilla-snapshot, /usr/lib/netscape/base-4/wrapper

39 SELinux defines process types (domains) for each process running on the
40 system
41 You can see the context of a process using the -Z option to ps
43 Policy governs the access confined processes have to files. SELinux
45 mozilla policy is very flexible allowing users to setup their mozilla
46 processes in as secure a method as possible.
47 The following process types are defined for mozilla:
49 mozilla_t, mozilla_plugin_t, mozilla_plugin_config_t
51 Note: semanage permissive -a mozilla_t can be used to make the process
53 type mozilla_t permissive. SELinux does not deny access to permissive
54 process types, but the AVC (SELinux denials) messages are still gener‐
55 ated.
56
59 SELinux policy is customizable based on least access required. mozilla
60 policy is extremely flexible and has several booleans that allow you to
61 manipulate the policy and run mozilla with the tightest access possi‐
62 ble.
63 If you want to allow confined web browsers to read home directory con‐
67 tent, you must turn on the mozilla_read_content boolean. Disabled by
68 default.
69 setsebool -P mozilla_read_content 1
71 If you want to allow users to resolve user passwd entries directly from
75 ldap rather then using a sssd server, you must turn on the authlo‐
76 gin_nsswitch_use_ldap boolean. Disabled by default.
77 setsebool -P authlogin_nsswitch_use_ldap 1
79 If you want to deny user domains applications to map a memory region as
83 both executable and writable, this is dangerous and the executable
84 should be reported in bugzilla, you must turn on the deny_execmem bool‐
85 ean. Enabled by default.
86 setsebool -P deny_execmem 1
88 If you want to allow all domains to execute in fips_mode, you must turn
92 on the fips_mode boolean. Enabled by default.
93 setsebool -P fips_mode 1
95 If you want to allow confined applications to run with kerberos, you
99 must turn on the kerberos_enabled boolean. Enabled by default.
100 setsebool -P kerberos_enabled 1
102 If you want to allow system to run with NIS, you must turn on the
106 nis_enabled boolean. Disabled by default.
107 setsebool -P nis_enabled 1
109 If you want to allow confined applications to use nscd shared memory,
113 you must turn on the nscd_use_shm boolean. Enabled by default.
114 setsebool -P nscd_use_shm 1
116 If you want to allow regular users direct dri device access, you must
120 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
121 setsebool -P selinuxuser_direct_dri_enabled 1
123 If you want to allow unconfined executables to make their stack exe‐
127 cutable. This should never, ever be necessary. Probably indicates a
128 badly coded executable, but could indicate an attack. This executable
129 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
130 stack boolean. Enabled by default.
131 setsebool -P selinuxuser_execstack 1
133 If you want to allows clients to write to the X server shared memory
137 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
138 abled by default.
139 setsebool -P xserver_clients_write_xshm 1
141
145 The SELinux process type mozilla_t can manage files labeled with the
146 following file types. The paths listed are the default paths for these
147 file types. Note the processes UID still need to have DAC permissions.

236 SELinux requires files to have an extended attribute to define the file
237 type.
238 You can see the context of a file using the -Z option to ls
240 Policy governs the access confined processes have to these files.
242 SELinux mozilla policy is very flexible allowing users to setup their
243 mozilla processes in as secure a method as possible.
244 STANDARD FILE CONTEXT
246 SELinux defines the file context types for the mozilla, if you wanted
248 to store files with these types in a diffent paths, you need to execute
249 the semanage command to sepecify alternate labeling and then use
250 restorecon to put the labels on disk.
251 semanage fcontext -a -t mozilla_tmpfs_t '/srv/mymozilla_content(/.*)?'
253 restorecon -R -v /srv/mymozilla_content
254 Note: SELinux often uses regular expressions to specify labels that
256 match multiple files.
257 The following file types are defined for mozilla:
259 mozilla_conf_t
263 - Set files with the mozilla_conf_t type, if you want to treat the
265 files as mozilla configuration data, usually stored under the /etc
266 directory.
267 mozilla_exec_t
271 - Set files with the mozilla_exec_t type, if you want to transition an
273 executable to the mozilla_t domain.
274 Paths:
277 /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*fire‐
278 fox[^/]*/firefox-bin, /usr/lib/mozilla[^/]*/reg.+, /usr/lib/fire‐
279 fox[^/]*/mozilla-.*, /usr/lib/mozilla[^/]*/mozilla-.*,

284 snapshot, /usr/lib/netscape/base-4/wrapper
285 mozilla_home_t
288 - Set files with the mozilla_home_t type, if you want to store mozilla
290 files in the users home directory.
291 Paths:
294 /home/[^/]+/.lyx(/.*)?, /home/[^/]+/.java(/.*)?,
295 /home/[^/]+/.adobe(/.*)?, /home/[^/]+/.gnash(/.*)?,

308 /home/[^/]+/.gnashpluginrc
309 mozilla_plugin_config_exec_t
312 - Set files with the mozilla_plugin_config_exec_t type, if you want to
314 transition an executable to the mozilla_plugin_config_t domain.
315 mozilla_plugin_exec_t
319 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
321 tion an executable to the mozilla_plugin_t domain.
322 Paths:
325 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
326 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
327 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-con‐
328 tainer
329 mozilla_plugin_rw_t
332 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
334 files as mozilla plugin read/write content.
335 mozilla_plugin_tmp_t
339 - Set files with the mozilla_plugin_tmp_t type, if you want to store
341 mozilla plugin temporary files in the /tmp directories.
342 mozilla_plugin_tmpfs_t
346 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
348 mozilla plugin files on a tmpfs file system.
349 mozilla_tmp_t
353 - Set files with the mozilla_tmp_t type, if you want to store mozilla
355 temporary files in the /tmp directories.
356 mozilla_tmpfs_t
360 - Set files with the mozilla_tmpfs_t type, if you want to store mozilla
362 files on a tmpfs file system.
363 Note: File context can be temporarily modified with the chcon command.
367 If you want to permanently change the file context you need to use the
368 semanage fcontext command. This will modify the SELinux labeling data‐
369 base. You will need to use restorecon to apply the labels.
370
373 semanage fcontext can also be used to manipulate default file context
374 mappings.
375 semanage permissive can also be used to manipulate whether or not a
377 process type is permissive.
378 semanage module can also be used to enable/disable/install/remove pol‐
380 icy modules.
381 semanage boolean can also be used to manipulate the booleans
383 system-config-selinux is a GUI tool available to customize SELinux pol‐
386 icy settings.
