Could be a dupe of #1172774 but the avc was different, so I'm not sure. *** This bug has been marked as a duplicate of bug 1172774 *** |
Description of problem: Run via cron by freshclam (the clamav database update). The antivirus_can_scan_system does not apply because freshclam is not doing an anti-virus scan. I think the Plugin that reports this solution with such high confidence should not consider freshclam within the antivirus scanning category. Not sure why freshclam needs access to /proc/filesystems. SELinux is preventing /usr/bin/freshclam from 'open' accesses on the file /proc/filesystems. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow antivirus programs to read non security files on a system Then you must tell SELinux about this by enabling the 'antivirus_can_scan_system' boolean. You can read 'antivirus_selinux' man page for more details. Do setsebool -P antivirus_can_scan_system 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that freshclam should be allowed open access on the filesystems file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep freshclam /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:antivirus_t:s0-s0:c0.c1023 Target Context system_u:object_r:proc_t:s0 Target Objects /proc/filesystems [ file ] Source freshclam Source Path /usr/bin/freshclam Port <Unknown> Host (removed) Source RPM Packages clamav-update-0.98.5-1.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-103.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.17.7-300.fc21.x86_64 #1 SMP Wed Dec 17 03:08:44 UTC 2014 x86_64 x86_64 Alert Count 1 First Seen 2015-01-05 15:25:41 EST Last Seen 2015-01-05 15:25:41 EST Local ID 821dd947-3077-4a31-9690-0516a11ad2ff Raw Audit Messages type=AVC msg=audit(1420489541.939:2092): avc: denied { open } for pid=15511 comm="freshclam" path="/proc/filesystems" dev="proc" ino=4026532041 scontext=system_u:system_r:antivirus_t:s0-s0:c0.c1023 tcontext=system_u:object_r:proc_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1420489541.939:2092): arch=x86_64 syscall=open success=no exit=EACCES a0=3cb1bc37d8 a1=0 a2=1b6 a3=240 items=0 ppid=15509 pid=15511 auid=0 uid=988 gid=980 euid=988 suid=988 fsuid=988 egid=980 sgid=980 fsgid=980 tty=(none) ses=29 comm=freshclam exe=/usr/bin/freshclam subj=system_u:system_r:antivirus_t:s0-s0:c0.c1023 key=(null) Hash: freshclam,antivirus_t,proc_t,file,open Version-Release number of selected component: selinux-policy-3.13.1-103.fc21.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 3.17.7-300.fc21.x86_64 type: libreport
