Description Elias Oliveira de Jesus 2013-11-27 20:17:33 UTC
Description of problem:
SELinux is preventing /usr/bin/clamscan from 'read' accesses on the file /var/lib/clamav-unofficial-sigs/ss-dbs/rogue.hdb.

*****  Plugin restorecon (92.2 confidence) suggests  *************************

If você deseja reparar este rótulo.
/var/lib/clamav-unofficial-sigs/ss-dbs/rogue.hdb rótulo padrão deve ser var_lib_t.
Then você pode executar o restorecon.
Do
# /sbin/restorecon -v /var/lib/clamav-unofficial-sigs/ss-dbs/rogue.hdb

*****  Plugin catchall_boolean (7.83 confidence) suggests  *******************

If você deseja allow antivirus to can scan system
Then you must tell SELinux about this by enabling the 'antivirus_can_scan_system' boolean.
You can read 'None' man page for more details.
Do
setsebool -P antivirus_can_scan_system 1

*****  Plugin catchall (1.41 confidence) suggests  ***************************

If você acredita que o clamscan deva ser permitido acesso de read em rogue.hdb file  por default.
Then você precisa reportar este como um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso agora executando:
# grep clamscan /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Did you add this labeling? 

Try to execute

# chcon -R -t antivirus_db_t /var/lib/clamav-unofficial-sigs
