Hi, I'm running SELinux in enforcing mode on fully updated CentOS-5 servers. selinux-policy-targeted-2.4.6-279.el5_5.2.noarch After an upgrade of selinux-policy-targeted last night I'm seeing the following AVC on several of the servers. [root@garryowen ~]# sealert -l badcaefe-41c9-4fcc-a264-24bff72bcfd7 Summary: SELinux is preventing iptables (iptables_t) "read write" to socket (initrc_t). Detailed Description: SELinux denied access requested by iptables. It is not expected that this access is required by iptables 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.
