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 deny user domains applications to map a memory region as
75 both executable and writable, this is dangerous and the executable
76 should be reported in bugzilla, you must turn on the deny_execmem bool‐
77 ean. Disabled by default.
78 setsebool -P deny_execmem 1
80 If you want to allow all domains to execute in fips_mode, you must turn
84 on the fips_mode boolean. Enabled by default.
85 setsebool -P fips_mode 1
87 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92 setsebool -P nis_enabled 1
94 If you want to allow regular users direct dri device access, you must
98 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
99 setsebool -P selinuxuser_direct_dri_enabled 1
101 If you want to allow unconfined executables to make their stack exe‐
105 cutable. This should never, ever be necessary. Probably indicates a
106 badly coded executable, but could indicate an attack. This executable
107 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
108 stack boolean. Enabled by default.
109 setsebool -P selinuxuser_execstack 1
111 If you want to support NFS home directories, you must turn on the
115 use_nfs_home_dirs boolean. Disabled by default.
116 setsebool -P use_nfs_home_dirs 1
118 If you want to support SAMBA home directories, you must turn on the
122 use_samba_home_dirs boolean. Disabled by default.
123 setsebool -P use_samba_home_dirs 1
125 If you want to allows clients to write to the X server shared memory
129 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
130 abled by default.
131 setsebool -P xserver_clients_write_xshm 1
133
137 The SELinux process type mozilla_t can manage files labeled with the
138 following file types. The paths listed are the default paths for these
139 file types. Note the processes UID still need to have DAC permissions.

233 SELinux requires files to have an extended attribute to define the file
234 type.
235 You can see the context of a file using the -Z option to ls
237 Policy governs the access confined processes have to these files.
239 SELinux mozilla policy is very flexible allowing users to setup their
240 mozilla processes in as secure a method as possible.
241 STANDARD FILE CONTEXT
243 SELinux defines the file context types for the mozilla, if you wanted
245 to store files with these types in a different paths, you need to exe‐
246 cute the semanage command to specify alternate labeling and then use
247 restorecon to put the labels on disk.
248 semanage fcontext -a -t mozilla_exec_t '/srv/mozilla/content(/.*)?'
250 restorecon -R -v /srv/mymozilla_content
251 Note: SELinux often uses regular expressions to specify labels that
253 match multiple files.
254 The following file types are defined for mozilla:
256 mozilla_conf_t
260 - Set files with the mozilla_conf_t type, if you want to treat the
262 files as mozilla configuration data, usually stored under the /etc di‐
263 rectory.
264 mozilla_exec_t
268 - Set files with the mozilla_exec_t type, if you want to transition an
270 executable to the mozilla_t domain.
271 Paths:
274 /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*fire‐
275 fox[^/]*/firefox-bin, /usr/lib/mozilla[^/]*/reg.+, /usr/lib/fire‐
276 fox[^/]*/mozilla-.*, /usr/lib/mozilla[^/]*/mozilla-.*,
277 /usr/bin/mozilla-[0-9].*, /usr/lib/netscape/.+/communicator/commu‐
278 nicator-smotif.real, /usr/bin/mozilla-bin-[0-9].*,

280 /usr/bin/epiphany-bin, /usr/lib/galeon/galeon, /usr/bin/mozilla-
281 snapshot, /usr/lib/netscape/base-4/wrapper
282 mozilla_home_t
285 - Set files with the mozilla_home_t type, if you want to store mozilla
287 files in the users home directory.
288 Paths:
291 /home/[^/]+/.lyx(/.*)?, /home/[^/]+/.java(/.*)?,
292 /home/[^/]+/.adobe(/.*)?, /home/[^/]+/.gnash(/.*)?,
293 /home/[^/]+/.webex(/.*)?, /home/[^/]+/.IBMERS(/.*)?,

304 /home/[^/]+/mozilla.pdf, /home/[^/]+/.gnashpluginrc
305 mozilla_plugin_config_exec_t
308 - Set files with the mozilla_plugin_config_exec_t type, if you want to
310 transition an executable to the mozilla_plugin_config_t domain.
311 mozilla_plugin_exec_t
315 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
317 tion an executable to the mozilla_plugin_t domain.
318 Paths:
321 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
322 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
323 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-con‐
324 tainer
325 mozilla_plugin_rw_t
328 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
330 files as mozilla plugin read/write content.
331 mozilla_plugin_tmp_t
335 - Set files with the mozilla_plugin_tmp_t type, if you want to store
337 mozilla plugin temporary files in the /tmp directories.
338 mozilla_plugin_tmpfs_t
342 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
344 mozilla plugin files on a tmpfs file system.
345 mozilla_tmp_t
349 - Set files with the mozilla_tmp_t type, if you want to store mozilla
351 temporary files in the /tmp directories.
352 mozilla_tmpfs_t
356 - Set files with the mozilla_tmpfs_t type, if you want to store mozilla
358 files on a tmpfs file system.
359 Note: File context can be temporarily modified with the chcon command.
363 If you want to permanently change the file context you need to use the
364 semanage fcontext command. This will modify the SELinux labeling data‐
365 base. You will need to use restorecon to apply the labels.
366
369 semanage fcontext can also be used to manipulate default file context
370 mappings.
371 semanage permissive can also be used to manipulate whether or not a
373 process type is permissive.
374 semanage module can also be used to enable/disable/install/remove pol‐
376 icy modules.
377 semanage boolean can also be used to manipulate the booleans
379 system-config-selinux is a GUI tool available to customize SELinux pol‐
382 icy settings.
