The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200905-08
(NTP: Remote execution of arbitrary code)
Multiple vulnerabilities have been found in the programs included in
the NTP package:
Apple Product Security reported a
boundary error in the cookedprint() function in ntpq/ntpq.c, possibly
leading to a stack-based buffer overflow (CVE-2009-0159).
Chris Ries of CMU reported a boundary error within the
crypto_recv() function in ntpd/ntp_crypto.c, possibly leading to a
stack-based buffer overflow (CVE-2009-1252).
A remote attacker might send a specially crafted package to a machine
running ntpd, possibly resulting in the remote execution of arbitrary
code with the privileges of the user running the daemon, or a Denial of
Service. NOTE: Successful exploitation requires the 'autokey' feature
to be enabled. This feature is only available if NTP was built with the
'ssl' USE flag.
Furthermore, a remote attacker could entice a user into connecting to a
malicious server using ntpq, possibly resulting in the remote execution
of arbitrary code with the privileges of the user running the
application, or a Denial of Service.
You can protect against CVE-2009-1252 by disabling the 'ssl' USE flag
and recompiling NTP.
