/dev/null: Permission denied

I dont know why the permission of /dev/null becomes 0600:
[code]
[color=blue]-(dearvoid@LinuxEden:tty3)-(~)-
[3968 0] # [/color]l /dev/null
crw------- 1 root root 1, 3 2006-05-31 09:15 /dev/null
[color=blue]-(dearvoid@LinuxEden:tty3)-(~)-
[3968 0] # [/color]o
[/code]
This causes non-root users to fail to write to /dev/null:
[code]
[color=blue]-(dearvoid@LinuxEden:tty3)-(~)-
[17086 0] # [/color]whoami
ubuntu
[color=blue]-(dearvoid@LinuxEden:tty3)-(~)-
[17086 0] # [/color]ls 2> /dev/null
-su: /dev/null: Permission denied
[color=blue]-(dearvoid@LinuxEden:tty3)-(~)-
[17086 1] # [/color]o
[/code]
Anyone has any idea?
