SELinux is preventing amavisd from using the dac_override capability. ***** 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 amavisd 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 'amavisd' --raw | audit2allow -M my-amavisd # semodule -X 300 -i my-amavisd.pp Additional Information: Source Context system_u:system_r:antivirus_t:s0 Target Context system_u:system_r:antivirus_t:s0 Target Objects Unknown [ capability ] Source amavisd Source Path amavisd Port <Unknown> Host helio Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.1-21.fc28.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name helio Platform Linux helio 4.16.2-300.fc28.x86_64 #1 SMP Thu Apr 12 14:58:07 UTC 2018 x86_64 x86_64 Alert Count 15 First Seen 2018-04-17 16:08:25 CEST Last Seen 2018-04-17 18:13:48 CEST Local ID 8f04bc4b-331a-4dd6-840b-9ad69aee5269 Raw Audit Messages type=AVC msg=audit(1523981628.373:570): avc: denied { dac_override } for pid=3667 comm="amavisd" capability=1 scontext=system_u:system_r:antivirus_t:s0 tcontext=system_u:system_r:antivirus_t:s0 tclass=capability permissive=0 Hash: amavisd,antivirus_t,antivirus_t,capability,dac_override
