NAME

6       abrt_handle_event_selinux  -  Security  Enhanced  Linux  Policy for the
7       abrt_handle_event processes
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  abrt_handle_event  processes  via
11       flexible mandatory access control.
12
13       The  abrt_handle_event  processes  execute with the abrt_handle_event_t
14       SELinux type. You can check if you have these processes running by exe‐
15       cuting the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep abrt_handle_event_t
20

22

ENTRYPOINTS

24       The  abrt_handle_event_t  SELinux type can be entered via the abrt_han‐
25       dle_event_exec_t file type.
26
27       The default entrypoint paths for the abrt_handle_event_t domain are the
28       following:
29
30       /usr/libexec/abrt-handle-event, /usr/bin/abrt-action-generate-backtrace
31

PROCESS TYPES

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       abrt_handle_event policy is very flexible allowing users to setup their
40       abrt_handle_event processes in as secure a method as possible.
41
42       The following process types are defined for abrt_handle_event:
43
44       abrt_handle_event_t
45
46       Note: semanage permissive -a abrt_handle_event_t can be  used  to  make
47       the  process type abrt_handle_event_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       abrt_handle_event policy is extremely flexible and has several booleans
55       that  allow you to manipulate the policy and run abrt_handle_event with
56       the tightest access possible.
57
58
59
60       If you want to deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If  you  want  to control the ability to mmap a low area of the address
70       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
71       the mmap_low_allowed boolean. Disabled by default.
72
73       setsebool -P mmap_low_allowed 1
74
75
76
77       If  you want to disable kernel module loading, you must turn on the se‐
78       cure_mode_insmod boolean. Enabled by default.
79
80       setsebool -P secure_mode_insmod 1
81
82
83
84       If you want to allow unconfined executables to make their  heap  memory
85       executable.   Doing  this  is  a  really bad idea. Probably indicates a
86       badly coded executable, but could indicate an attack.  This  executable
87       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
88       echeap boolean. Disabled by default.
89
90       setsebool -P selinuxuser_execheap 1
91
92
93
94       If you want to allow unconfined executables to make  their  stack  exe‐
95       cutable.   This  should  never, ever be necessary. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
98       stack boolean. Enabled by default.
99
100       setsebool -P selinuxuser_execstack 1

MANAGED FILES

105       The SELinux process type abrt_handle_event_t can manage  files  labeled
106       with  the following file types.  The paths listed are the default paths
107       for these file types.  Note the processes UID still need  to  have  DAC
108       permissions.
109
110       file_type
111
112            all files on the system
113
114

FILE CONTEXTS

116       SELinux requires files to have an extended attribute to define the file
117       type.
118
119       You can see the context of a file using the -Z option to ls
120
121       Policy governs the access  confined  processes  have  to  these  files.
122       SELinux  abrt_handle_event  policy  is  very flexible allowing users to
123       setup their abrt_handle_event processes in as secure a method as possi‐
124       ble.
125
126       The following file types are defined for abrt_handle_event:
127
128
129
130       abrt_handle_event_exec_t
131
132       -  Set  files  with  the  abrt_handle_event_exec_t type, if you want to
133       transition an executable to the abrt_handle_event_t domain.
134
135
136       Paths:
137            /usr/libexec/abrt-handle-event,     /usr/bin/abrt-action-generate-
138            backtrace
139
140
141       Note:  File context can be temporarily modified with the chcon command.
142       If you want to permanently change the file context you need to use  the
143       semanage fcontext command.  This will modify the SELinux labeling data‐
144       base.  You will need to use restorecon to apply the labels.
145
146

COMMANDS

148       semanage fcontext can also be used to manipulate default  file  context
149       mappings.
150
151       semanage  permissive  can  also  be used to manipulate whether or not a
152       process type is permissive.
153
154       semanage module can also be used to enable/disable/install/remove  pol‐
155       icy modules.
156
157       semanage boolean can also be used to manipulate the booleans
158
159
160       system-config-selinux is a GUI tool available to customize SELinux pol‐
161       icy settings.
