sysadm_mozilla_selinux − Security Enhanced Linux Policy for the sysadm_mozilla processes
Security-Enhanced Linux secures the sysadm_mozilla processes via flexible mandatory access control.
The sysadm_mozilla processes execute with the sysadm_mozilla_t SELinux type. You can check if you have these processes running by executing the ps command with the −Z qualifier.
For example:
ps -eZ | grep sysadm_mozilla_t
The sysadm_mozilla_t SELinux type can be entered via the sysadm_home_dir_t, sysadm_home_t, mozilla_exec_t file types.
The default entrypoint paths for the sysadm_mozilla_t domain are the following:
/root, /root/(.*)?, /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*firefox[^/]*/firefox-bin, /usr/lib64/[^/]*firefox[^/]*/firefox, /usr/lib64/[^/]*firefox[^/]*/firefox-bin, /usr/lib/mozilla[^/]*/reg.+, /usr/lib/mozilla[^/]*/mozilla-.*, /usr/lib/firefox[^/]*/mozilla-.*, /usr/bin/mozilla-[0-9].*, /usr/lib64/mozilla[^/]*/reg.+, /usr/lib64/mozilla[^/]*/mozilla-.*, /usr/lib64/firefox[^/]*/mozilla-.*, /usr/lib/netscape/.+/communicator/communicator-smotif.real, /usr/lib64/netscape/.+/communicator/communicator-smotif.real, /usr/bin/mozilla-bin-[0-9].*, /usr/bin/mozilla, /usr/bin/netscape, /usr/bin/epiphany, /usr/bin/epiphany-bin, /usr/lib/galeon/galeon, /usr/lib64/galeon/galeon, /usr/bin/mozilla-snapshot, /usr/lib/netscape/base-4/wrapper, /usr/lib64/netscape/base-4/wrapper
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 ps
Policy governs the access confined processes have to files. SELinux sysadm_mozilla policy is very flexible allowing users to setup their sysadm_mozilla processes in as secure a method as possible.
The following process types are defined for sysadm_mozilla:
sysadm_mozilla_t
Note: semanage permissive -a sysadm_mozilla_t can be used to make the process type sysadm_mozilla_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. sysadm_mozilla policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sysadm_mozilla with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Enabled by default.
setsebool -P deny_execmem 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow confined web browsers to read home directory content, you must turn on the mozilla_read_content boolean. Disabled by default.
setsebool -P mozilla_read_content 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Enabled by default.
setsebool -P selinuxuser_execstack 1
If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the sysadm_mozilla_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the sysadm_mozilla_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
The SELinux process type sysadm_mozilla_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
