- CVEs with nessus.description==Multiple buffer overflow flaws were discovered in ntpd's
crypto_recv(), ctl_putdata(), and configure() functions. A remote
attacker could use either of these flaws to send a specially crafted
request packet that could crash ntpd or, potentially, execute
arbitrary code with the privileges of the ntp user. Note: the
crypto_recv() flaw requires non- default configurations to be active,
while the ctl_putdata() flaw, by default, can only be exploited via
local attackers, and the configure() flaw requires additional
authentication to exploit. (CVE-2014-9295)
It was found that ntpd automatically generated weak keys for its
internal use if no ntpdc request authentication key was specified in
the ntp.conf configuration file. A remote attacker able to match the
configured IP restrictions could guess the generated key, and possibly
use it to send ntpdc query or configuration requests. (CVE-2014-9293)
It was found that ntp-keygen used a weak method for generating MD5
keys. This could possibly allow an attacker to guess generated MD5
keys that could then be used to spoof an NTP client or server. Note:
it is recommended to regenerate any MD5 keys that had explicitly been
generated with ntp-keygen; the default installation does not contain
such keys). (CVE-2014-9294)
A missing return statement in the receive() function could potentially
allow a remote attacker to bypass NTP's authentication mechanism.
(CVE-2014-9296)
After installing the update, the ntpd daemon will restart
automatically.
