hi!  
  
there is bug with 64 bit solaris 7 procfs, every [nonprivileged] user can  
crash computer with command 'more /proc/self/psinfo'. Tested with UE3000,  
U10, UE450. This bug has been reported to Sun, with no response.

It was previously reported on bugtraq that the command  
"/usr/xpg4/bin/more /proc/self/psinfo" will crash U10, UE3000,  
etc. running SunOS 5.7.  
  
Sun is aware of this (has assigned a bugid):

Hi!  
  
some more information about this very issue.  
  
both (32bit,64bit) sparc versions of Solaris 7 can be crashed by  
unprivileged user. /usr/xpg4/bin/more command will trigger the bug. FYI  
I got message from Sun kernel developer team member only minutes after  
my e-mail to bugtraq and after some consultation they were able to  
reproduce bug and find the cause, so expect patch soon.  
  
intel version of solaris 7 seems to be immune to this bug, however.  
  
with this, I'd like to close this issue. please send questions about  
this not for me, but Sun :)
