dbus patch for CVE-2008-4311 introduces logging of denied message bus messages. To make the messages more useful, dbus-daemon reads /proc/*/cmdline and include its content in log message. Such access is, however, prohibited by current selinux-policy in Red Hat Enterprise Linux 5. To avoid AVCs for dbus log messages, policy should allow dbus-daemon to: domain_read_all_domains_state(system_dbusd_t) Note: this fix is already included in selinux-policy in Rawhide / Fedora 11.
Fixed in selinux-policy-3.6.9-4.el5
Oops make that Fixed in selinux-policy-2.4.6-217.el5
This won't get fixed in 5.3.z, but is fixed in 5.4.
