6 wine_selinux - Security Enhanced Linux Policy for the wine processes
7
9 Security-Enhanced Linux secures the wine processes via flexible manda‐
10 tory access control.
11
12 The wine processes execute with the wine_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep wine_t
19
20
21
23 The wine_t SELinux type can be entered via the wine_exec_t file type.
24
25 The default entrypoint paths for the wine_t domain are the following:
26
27 /usr/bin/wine.*, /opt/teamviewer(/.*)?/bin/wine.*,
28 /opt/google/picasa(/.*)?/bin/wdi, /opt/google/picasa(/.*)?/bin/wine.*,
29 /opt/google/picasa(/.*)?/bin/msiexec,
30 /opt/google/picasa(/.*)?/bin/notepad,
31 /opt/google/picasa(/.*)?/bin/progman,
32 /opt/google/picasa(/.*)?/bin/regedit,
33 /opt/google/picasa(/.*)?/bin/regsvr32,
34 /opt/google/picasa(/.*)?/Picasa3/.*exe,
35 /opt/google/picasa(/.*)?/bin/uninstaller, /opt/cxoffice/bin/wine.*,
36 /opt/picasa/wine/bin/wine.*, /usr/bin/msiexec, /usr/bin/notepad,
37 /usr/bin/regedit, /usr/bin/regsvr32, /usr/bin/uninstaller,
38 /home/[^/]+/cxoffice/bin/wine.+

41 SELinux defines process types (domains) for each process running on the
42 system
43
44 You can see the context of a process using the -Z option to ps
45
46 Policy governs the access confined processes have to files. SELinux
47 wine policy is very flexible allowing users to setup their wine pro‐
48 cesses in as secure a method as possible.
49
50 The following process types are defined for wine:
51
52 wine_t
53
54 Note: semanage permissive -a wine_t can be used to make the process
55 type wine_t permissive. SELinux does not deny access to permissive
56 process types, but the AVC (SELinux denials) messages are still gener‐
57 ated.
58
59
61 SELinux policy is customizable based on least access required. wine
62 policy is extremely flexible and has several booleans that allow you to
63 manipulate the policy and run wine with the tightest access possible.
64
65
66
67 If you want to deny user domains applications to map a memory region as
68 both executable and writable, this is dangerous and the executable
69 should be reported in bugzilla, you must turn on the deny_execmem bool‐
70 ean. Enabled by default.
71
72 setsebool -P deny_execmem 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to control the ability to mmap a low area of the address
84 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
85 the mmap_low_allowed boolean. Disabled by default.
86
87 setsebool -P mmap_low_allowed 1
88
89
90
91 If you want to disable kernel module loading, you must turn on the
92 secure_mode_insmod boolean. Enabled by default.
93
94 setsebool -P secure_mode_insmod 1
95
96
97
98 If you want to allow unconfined executables to make their heap memory
99 executable. Doing this is a really bad idea. Probably indicates a
100 badly coded executable, but could indicate an attack. This executable
101 should be reported in bugzilla, you must turn on the selin‐
102 uxuser_execheap boolean. Disabled by default.
103
104 setsebool -P selinuxuser_execheap 1
105
106
107
108 If you want to allow unconfined executables to make their stack exe‐
109 cutable. This should never, ever be necessary. Probably indicates a
110 badly coded executable, but could indicate an attack. This executable
111 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
112 stack boolean. Enabled by default.
113
114 setsebool -P selinuxuser_execstack 1
115
116
117
119 The SELinux process type wine_t can manage files labeled with the fol‐
120 lowing file types. The paths listed are the default paths for these
121 file types. Note the processes UID still need to have DAC permissions.
122
123 file_type
124
125 all files on the system
126
127
129 SELinux requires files to have an extended attribute to define the file
130 type.
131
132 You can see the context of a file using the -Z option to ls
133
134 Policy governs the access confined processes have to these files.
135 SELinux wine policy is very flexible allowing users to setup their wine
136 processes in as secure a method as possible.
137
138 STANDARD FILE CONTEXT
139
140 SELinux defines the file context types for the wine, if you wanted to
141 store files with these types in a diffent paths, you need to execute
142 the semanage command to sepecify alternate labeling and then use
143 restorecon to put the labels on disk.
144
145 semanage fcontext -a -t wine_home_t '/srv/mywine_content(/.*)?'
146 restorecon -R -v /srv/mywine_content
147
148 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150
151 The following file types are defined for wine:
152
153
154
155 wine_exec_t
156
157 - Set files with the wine_exec_t type, if you want to transition an
158 executable to the wine_t domain.
159
160
161 Paths:
162 /usr/bin/wine.*, /opt/teamviewer(/.*)?/bin/wine.*,
163 /opt/google/picasa(/.*)?/bin/wdi,
164 /opt/google/picasa(/.*)?/bin/wine.*,
165 /opt/google/picasa(/.*)?/bin/msiexec,
166 /opt/google/picasa(/.*)?/bin/notepad,
167 /opt/google/picasa(/.*)?/bin/progman,
168 /opt/google/picasa(/.*)?/bin/regedit,
169 /opt/google/picasa(/.*)?/bin/regsvr32,
170 /opt/google/picasa(/.*)?/Picasa3/.*exe,
171 /opt/google/picasa(/.*)?/bin/uninstaller, /opt/cxof‐
172 fice/bin/wine.*, /opt/picasa/wine/bin/wine.*, /usr/bin/msiexec,
173 /usr/bin/notepad, /usr/bin/regedit, /usr/bin/regsvr32,
174 /usr/bin/uninstaller, /home/[^/]+/cxoffice/bin/wine.+
175
176
177 wine_home_t
178
179 - Set files with the wine_home_t type, if you want to store wine files
180 in the users home directory.
181
182
183
184 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
189
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193
194 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196
197 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199
200 semanage boolean can also be used to manipulate the booleans
201
202
203 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
