Description:   Opened: 2009-03-19 13:03 0000 
** Please note that this issue is confidential and no information should be
disclosed until it is made public, see "Whiteboard" for a date **

Apple discovered a stack-based buffer overflow in the ntpq program. When  
the ntpq program is used to request peer information from a remote  
time server, a maliciously crafted response may lead to an unexpected  
application termination or arbitrary code execution.

The buffer overflow is limited to two bytes, so a code execution impact is
unlikely, but this is dependent on the stack layout generated by cc.

CVE-2009-0159 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0159):
  Stack-based buffer overflow in the cookedprint function in
  ntpq/ntpq.c in ntpq in NTP before 4.2.4p7-RC2 allows remote NTP
  servers to execute arbitrary code via a crafted response.

distfiles-local

------- Comment #9 From Ferris McCormick 2009-05-20 13:25:05 0000 ------- 
Sparc stable.  ntpd can run and seems to set up a working ntp, at least
according to 'ntpq -p' which still works as expected.  Tested by use, because I
use this on all my systems.
