SELinux is preventing /usr/bin/abrt-dump-oops (deleted) 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 abrt-dump-oops (deleted) 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 abrt-dump-oops /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
