SELinux is preventing clamd.scan (system_cronjob_t) "write" crond_t

[Edward Kuns]

Just in the past few days I've received seven of this AVC complaint, and
I haven't seen any of this complaint before that.  On 11 July, I updated
selinux to 3.6.12-62.fc11.  I currently have clamav-0.95.1-2.fc11.i586,
installed on 1 July.  I am not aware of anything that changed on or just
before the 17th.  Any ideas?

Here's the sealert:

	Thanks

Summary:

SELinux is preventing clamd.scan (system_cronjob_t) "write" crond_t.

Detailed Description:

SELinux denied access requested by clamd.scan. It is not expected that
this
access is required by clamd.scan 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can
disable
SELinux protection altogether. Disabling SELinux protection is not
recommended.
Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
