Description Frank Murphy 2010-07-24 05:04:14 EDT

SELinux is preventing /usr/bin/perl "entrypoint" access on /usr/sbin/exim.

Detailed Description:

SELinux denied access requested by logwatch. It is not expected that this access
is required by logwatch and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Miroslav, we are going to need this fix in F13 also.

	allow $2 mta_exec_type:file entrypoint;
