Description Horst H. von Brand 2011-01-17 14:16:19 UTC
SELinux is preventing /usr/sbin/sendmail.sendmail from 'read' accesses on the chr_file random.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that sendmail.sendmail should be allowed read access on the random chr_file 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 sendmail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-01-17 15:57:31 UTC
Since system mail can read this, I guess logwatch_mail should be allowed also.

Comment 2 Miroslav Grepl 2011-01-17 16:05:03 UTC
Fixed in selinux-policy-3.9.12-8.fc15
