Description of problem: SELinux is preventing /usr/bin/evince-thumbnailer from using the 'dac_override' capabilities. ***** Plugin dac_override (91.4 confidence) suggests *********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests *************************** If you believe that evince-thumbnailer should have the dac_override capability 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 evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 Target Context unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 Target Objects [ capability ] Source evince-thumbnai Source Path /usr/bin/evince-thumbnailer Port <Unknown> Host (removed) Source RPM Packages evince-3.6.1-2.fc18.x86_64 Target RPM Packages Policy RPM selinux-policy-3.11.1-66.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.6.10-4.fc18.x86_64 #1 SMP Tue Dec 11 18:01:27 UTC 2012 x86_64 x86_64 Alert Count 2 First Seen 2013-01-12 00:19:46 PST Last Seen 2013-01-12 00:19:46 PST Local ID c3a2161b-9413-4bf2-a8c4-3a46b466b550 Raw Audit Messages type=AVC msg=audit(1357978786.281:398): avc: denied { dac_override } for pid=3369 comm="evince-thumbnai" capability=1 scontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tclass=capability type=AVC msg=audit(1357978786.281:398): avc: denied { dac_read_search } for pid=3369 comm="evince-thumbnai" capability=2 scontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tclass=capability type=SYSCALL msg=audit(1357978786.281:398): arch=x86_64 syscall=open success=no exit=EACCES a0=137e980 a1=0 a2=0 a3=aaaaaaaaaaaaaaab items=0 ppid=3345 pid=3369 auid=1000 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=2 comm=evince-thumbnai exe=/usr/bin/evince-thumbnailer subj=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 key=(null) Hash: evince-thumbnai,thumb_t,thumb_t,capability,dac_override audit2allow audit2allow -R Additional info: hashmarkername: setroubleshoot kernel: 3.6.10-4.fc18.x86_64 type: libreport Potential duplicate: bug 815106
