Description of problem: SELinux is preventing sendmail 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 sendmail 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 'sendmail' --raw | audit2allow -M my-sendmail # semodule -X 300 -i my-sendmail.pp Additional Information: Source Context system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 Target Context system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source sendmail Source Path sendmail Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.3-46.fc30.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.2.18-200.fc30.x86_64 #1 SMP Tue Oct 1 13:14:07 UTC 2019 x86_64 x86_64 Alert Count 3 First Seen 2019-10-10 13:18:07 MSK Last Seen 2019-10-12 11:36:06 MSK Local ID 9fc5d941-2b28-431e-96dd-3c5b076a6265 Raw Audit Messages type=AVC msg=audit(1570869366.280:387): avc: denied { dac_override } for pid=10620 comm="sendmail" capability=1 scontext=system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 tcontext=system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 tclass=capability permissive=0 Hash: sendmail,logwatch_mail_t,logwatch_mail_t,capability,dac_override Version-Release number of selected component: selinux-policy-3.14.3-46.fc30.noarch Additional info: component: selinux-policy reporter: libreport-2.10.1 hashmarkername: setroubleshoot kernel: 5.2.18-200.fc30.x86_64 type: libreport
