Synopsis: Critical: ntp security update
Issue date: 2009-05-18
CVE Names: CVE-2009-0159 CVE-2009-1252
A buffer overflow flaw was discovered in the ntpd daemon's NTPv4
authentication code. If ntpd was configured to use public key
cryptography for NTP packet authentication, a remote attacker could use
this flaw to send a specially-crafted request packet that could crash
ntpd or, potentially, execute arbitrary code with the privileges of the
"ntp" user. (CVE-2009-1252)
Note: NTP authentication is not enabled by default.
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)
After installing the update, the ntpd daemon will be restarted
automatically.
