"CVE-2009-0159 ntp: buffer overflow in ntpq

CVE-2009-3563 ntpd: DoS with mode 7 packets (VU#568372)

Robin Park and Dmitri Vinokurov discovered a flaw in the way ntpd
handled certain malformed NTP packets. ntpd logged information about
all such packets and replied with an NTP packet that was treated as
malformed when received by another ntpd. A remote attacker could use
this flaw to create an NTP packet reply loop between two ntpd servers
via a malformed packet with a spoofed source IP address and port,
causing ntpd on those servers to use excessive amounts of CPU time and
fill disk space with log messages. (CVE-2009-3563)

A buffer overflow flaw was found in the ntpq diagnostic command. A
malicious, remote server could send a specially crafted reply to an
ntpq request that could crash ntpq or, potentially, execute arbitrary
code with the privileges of the user running the ntpq command.
(CVE-2009-0159) SL3 Only

After installing the update, the ntpd daemon will restart
automatically."
