Description Rahul Sundaram 2009-07-19 19:18:08 UTC 
+++ This bug was initially created as a clone of Bug #511143 +++

I have a fix for this in selinux-policy-2.4.6-252.el5

The default SELinux policy allows processes in the unconfined domains to map low memory in the kernel. We are updating the selinux-policy package to allow the user to set the allow_unconfined_mmap_low boolean, and to prevent unconfined_t from being able to map low memory in the kernel. No Relabel or Reboot required.
Comment 1 Daniel Walsh 2009-07-20 20:38:43 UTC 
Fixed in selinux-policy-3.6.22-2.fc12
Comment 2 Rahul Sundaram 2009-07-20 20:50:18 UTC 
Dan,

I think you should push the policy update to Fedora 11 and Fedora 10 as well.
Comment 3 Daniel Walsh 2009-07-21 01:22:49 UTC 
Miroslav is preparing updates for F10 and F11.
