COMMAND
		FreeBSD boundary checking errors involving signed integers
SYSTEMS AFFECTED
		All releases of FreeBSD up to and including 4.6.1-RELEASE-p10
PROBLEM
		Thanks  to  Silvio  Cesare  [[email protected]],  in  FreeBSD   security
		advisory [FreeBSD-SA-02:38.signed-error] :
		--snipp--
		The  issue  described  in   this   advisory   affects   the   accept(2),
		getsockname(2),  and  getpeername(2)  system  calls,  and  the   vesa(4)
		FBIO_GETPALETTE ioctl(2).
		--snapp--
		A few system calls were identified that  contained  assumptions  that  a
		given argument  was  always  a  positive  integer,  while  in  fact  the
		argument was handled as a signed integer.  As  a  result,  the  boundary
		checking code would  fail  if  the  system  call  were  entered  with  a
		negative argument.

SOLUTION
