6 httpd_unconfined_script_selinux - Security Enhanced Linux Policy for
7 the httpd_unconfined_script processes
8
10 Security-Enhanced Linux secures the httpd_unconfined_script processes
11 via flexible mandatory access control.
12
13 The httpd_unconfined_script processes execute with the httpd_uncon‐
14 fined_script_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep httpd_unconfined_script_t
20
21
22
24 The httpd_unconfined_script_t SELinux type can be entered via the
25 httpd_unconfined_script_exec_t file type.
26
27 The default entrypoint paths for the httpd_unconfined_script_t domain
28 are the following:
29
30
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 httpd_unconfined_script policy is very flexible allowing users to setup
40 their httpd_unconfined_script processes in as secure a method as possi‐
41 ble.
42
43 The following process types are defined for httpd_unconfined_script:
44
45 httpd_unconfined_script_t
46
47 Note: semanage permissive -a httpd_unconfined_script_t can be used to
48 make the process type httpd_unconfined_script_t permissive. SELinux
49 does not deny access to permissive process types, but the AVC (SELinux
50 denials) messages are still generated.
51
52
54 SELinux policy is customizable based on least access required.
55 httpd_unconfined_script policy is extremely flexible and has several
56 booleans that allow you to manipulate the policy and run httpd_uncon‐
57 fined_script with the tightest access possible.

60
61 If you want to deny user domains applications to map a memory region as
62 both executable and writable, this is dangerous and the executable
63 should be reported in bugzilla, you must turn on the deny_execmem bool‐
64 ean. Enabled by default.
65
66 setsebool -P deny_execmem 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to control the ability to mmap a low area of the address
78 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
79 the mmap_low_allowed boolean. Disabled by default.
80
81 setsebool -P mmap_low_allowed 1
82
83
84
85 If you want to disable kernel module loading, you must turn on the
86 secure_mode_insmod boolean. Enabled by default.
87
88 setsebool -P secure_mode_insmod 1
89
90
91
92 If you want to allow unconfined executables to make their heap memory
93 executable. Doing this is a really bad idea. Probably indicates a
94 badly coded executable, but could indicate an attack. This executable
95 should be reported in bugzilla, you must turn on the selin‐
96 uxuser_execheap boolean. Disabled by default.
97
98 setsebool -P selinuxuser_execheap 1
99
100
101
102 If you want to allow unconfined executables to make their stack exe‐
103 cutable. This should never, ever be necessary. Probably indicates a
104 badly coded executable, but could indicate an attack. This executable
105 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
106 stack boolean. Disabled by default.
107
108 setsebool -P selinuxuser_execstack 1

113 The SELinux process type httpd_unconfined_script_t can manage files
114 labeled with the following file types. The paths listed are the
115 default paths for these file types. Note the processes UID still need
116 to have DAC permissions.
117
118 file_type
119
120 all files on the system
121
122
124 semanage fcontext can also be used to manipulate default file context
125 mappings.
126
127 semanage permissive can also be used to manipulate whether or not a
128 process type is permissive.
129
130 semanage module can also be used to enable/disable/install/remove pol‐
131 icy modules.
132
133 semanage boolean can also be used to manipulate the booleans
134
135
136 system-config-selinux is a GUI tool available to customize SELinux pol‐
137 icy settings.
