Bug ID: 2276
Summary: Exim triggers DAC_OVERRIDE when running on SELinux
enabled system
Product: Exim
Version: 4.91
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: General execution
Assignee: [email protected]

The problem is that it creates log file with mode 0640 and exim:exim owner.
Then it writes to it when running suid root which triggers DAC_OVERRIDE. The
same problem can be triggered with spool files. Problem occurs with
selinux-policy-3.14.1. Downstream Fedora 28 bugzilla:
