  "details" : [ "The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary." ],
  "statement" : "Red Hat Enterprise Linux 4 is now in Production 3 of the maintenance life-cycle,\nhttps://access.redhat.com/support/policy/updates/errata/, therefore the fix for\nthis issue is not currently planned to be included in the future updates. Future kernel updates in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG may address this flaw.",
