Description of problem: I assume deja-dup came pre-installed with Fedora 19. I have no idea what mmap is or what it does with memory. SELinux is preventing /usr/libexec/deja-dup/deja-dup-monitor from 'mmap_zero' accesses on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************** If you do not think /usr/libexec/deja-dup/deja-dup-monitor should need to mmap low memory in the kernel. Then you may be under attack by a hacker, this is a very dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to allow mmap to low allowed Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean. You can read 'None' man page for more details. Do setsebool -P mmap_low_allowed 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that deja-dup-monitor should be allowed mmap_zero access on the memprotect 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 64636F6E6620776F726B6572 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects [ memprotect ] Source 64636F6E6620776F726B6572 Source Path /usr/libexec/deja-dup/deja-dup-monitor Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.12.1-74.11.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.11.7-200.fc19.i686 #1 SMP Mon Nov 4 14:32:57 UTC 2013 i686 i686 Alert Count 4 First Seen 2013-11-08 22:25:13 EST Last Seen 2013-11-08 22:25:13 EST Local ID f96b1c63-689a-4a9a-9ca8-d729f6dfa222 Raw Audit Messages type=AVC msg=audit(1383967513.506:734): avc: denied { mmap_zero } for pid=1678 comm=64636F6E6620776F726B6572 scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=memprotect Hash: 64636F6E6620776F726B6572,unconfined_t,unconfined_t,memprotect,mmap_zero Additional info: reporter: libreport-2.1.9 hashmarkername: setroubleshoot kernel: 3.11.7-200.fc19.i686 type: libreport Potential duplicate: bug 1008852
