Seems to occur when spamassassin.service starts or is restarted. Hi, This looks more like packaging issue than SELinux policy one. Moving to proper component. For more info see: https://lukas-vrabec.com/index.php/2018/07/03/why-do-you-see-dac_override-selinux-denials/ IMHO it has been resolved in spamassassin-3.4.1-20, just merging it from the Rawhide and building it should be enough to resolve this problem. Yep. Can you build/submit the update? Or would you like me to? (In reply to Kevin Fenzi from comment #4) > Yep. Can you build/submit the update? Or would you like me to? OK, NP, I will do it. spamassassin-3.4.1-20.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-07cdeffc1e spamassassin-3.4.1-20.fc28 has been pushed to the Fedora 28 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-07cdeffc1e spamassassin-3.4.1-20.fc28 has been pushed to the Fedora 28 stable repository.

SELinux is preventing spamd 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 spamd 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: # ausearch -c 'spamd' --raw | audit2allow -M my-spamd # semodule -X 300 -i my-spamd.pp Additional Information: Source Context system_u:system_r:spamd_t:s0 Target Context system_u:system_r:spamd_t:s0 Target Objects Unknown [ capability ] Source spamd Source Path spamd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.1-32.fc28.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.16.14-300.fc28.x86_64 #1 SMP Tue Jun 5 16:23:44 UTC 2018 x86_64 x86_64 Alert Count 4 First Seen 2018-06-10 10:24:49 EDT Last Seen 2018-06-12 00:52:22 EDT Local ID 6910e659-ab84-4de8-8ec5-87fa51bf4015 Raw Audit Messages type=AVC msg=audit(1528779142.714:5790): avc: denied { dac_override } for pid=12914 comm="spamd" capability=1 scontext=system_u:system_r:spamd_t:s0 tcontext=system_u:system_r:spamd_t:s0 tclass=capability permissive=0 Hash: spamd,spamd_t,spamd_t,capability,dac_override
