Description maurizio 2011-01-23 01:54:04 UTC
Summary:

SELinux is preventing /usr/bin/python "read" access on random.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by sealert. It is not expected that this access
is required by sealert 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
report.
