NAME

mozilla_selinux - Security Enhanced Linux Policy for the mozilla processes

DESCRIPTION

SELinux Linux secures mozilla (Policy for Mozilla and related web browsers) processes via flexible mandatory access control.

BOOLEANS

SELinux policy is customizable based on least access required. mozilla policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mozilla with the tightest access possible.

If you want to control mozilla content acces, you must turn on the mozilla_read_content boolean.

setsebool -P mozilla_read_content 1

If you want to allow unconfined users to transition to the Mozilla plugin domain when running xulrunner plugin-container, you must turn on the unconfined_mozilla_plugin_transition boolean.

setsebool -P unconfined_mozilla_plugin_transition 1

FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux mozilla policy is very flexible allowing users to setup their mozilla processes in as secure a method as possible.

The following file types are defined for mozilla:

mozilla_conf_t

- Set files with the mozilla_conf_t type, if you want to treat the files as mozilla configuration data, usually stored under the /etc directory.

mozilla_exec_t

- Set files with the mozilla_exec_t type, if you want to transition an executable to the mozilla_t domain.

Paths:: /usr/lib(64)?/mozilla[^/]*/mozilla-.*, /usr/lib(64)?/netscape/.+/communicator/communicator-smotif.real, /usr/lib(64)?/galeon/galeon, /usr/lib(64)?/firefox[^/]*/mozilla-.*, /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib(64)?/mozilla[^/]*/reg.+, /usr/bin/netscape, /usr/bin/mozilla-bin-[0-9].*, /usr/bin/epiphany-bin, /usr/bin/mozilla-snapshot, /usr/lib(64)?/netscape/base-4/wrapper, /usr/lib64/[^/]*firefox[^/]*/firefox, /usr/bin/mozilla-[0-9].*, /usr/lib(64)?/[^/]*firefox[^/]*/firefox-bin, /usr/bin/mozilla, /usr/bin/epiphany

mozilla_home_t

- Set files with the mozilla_home_t type, if you want to store mozilla files in the users home directory.

mozilla_plugin_config_exec_t

- Set files with the mozilla_plugin_config_exec_t type, if you want to transition an executable to the mozilla_plugin_config_t domain.

mozilla_plugin_exec_t

- Set files with the mozilla_plugin_exec_t type, if you want to transition an executable to the mozilla_plugin_t domain.

mozilla_plugin_rw_t

- Set files with the mozilla_plugin_rw_t type, if you want to treat the files as mozilla plugin read/write content.

mozilla_plugin_tmp_t

- Set files with the mozilla_plugin_tmp_t type, if you want to store mozilla plugin temporary files in the /tmp directories.

mozilla_plugin_tmpfs_t

- Set files with the mozilla_plugin_tmpfs_t type, if you want to store mozilla plugin files on a tmpfs file system.

mozilla_tmpfs_t

- Set files with the mozilla_tmpfs_t type, if you want to store mozilla files on a tmpfs file system.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

PROCESS TYPES

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mozilla policy is very flexible allowing users to setup their mozilla processes in as secure a method as possible.

The following process types are defined for mozilla:

mozilla_t, mozilla_plugin_config_t, mozilla_plugin_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

COMMANDS

semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove policy modules.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
