NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

Bug fixes, enhancements. <p /> Severity: HIGH <p /> In addition to bug fixes and enhancements, this release fixes the following high-severity vulnerabilities: <p /> <strong>************************</strong> vv NOTE WELL vv <strong>***************************</strong> <p /> The vulnerabilities listed below can be significantly mitigated by following the BCP of putting <pre> restrict default ... noquery </pre> in the <code>ntp.conf file</code>. With the exception of: <p /> <ul> <li> <code>receive()</code> missing return on error - References: Sec 2670 / CVE-2014-9296 / VU#852879 </li></ul> <p /> below (which is a limited-risk vulnerability), none of the recent vulnerabilities listed below can be exploited if the source IP is restricted from sending a 'query'-class packet by your <code>ntp.conf</code> file. <p /> <strong>************************</strong> ^^ NOTE WELL ^^ <strong>***************************</strong> <p /> <h4><a name="Weak_default_key_in_config_auth"></a> Weak default key in <code>config_auth()</code>. </h4> <p /> <ul> <li> References: [Sec 2665] / CVE-2014-9293 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:M/C:P/I:P/A:C) Base Score: 7.3 </li> <li> Vulnerable Versions: all releases prior to 4.2.7p11 </li> <li> Date Resolved: 28 Jan 2010 </li></ul> <p /> <h5><a name="Summary"></a> Summary </h5> If no 'auth' key is set in the configuration file, <code>ntpd</code> would generate a random key on the fly. There were two problems with this: 1) the generated key was 31 bits in size, and 2) it used the (now weak) <code>ntp_random()</code> function, which was seeded with a 32-bit value and could only provide 32 bits of entropy. This was sufficient back in the late 1990s when the code was written. Not today. <p /> <h5><a name="Mitigation"></a> Mitigation </h5> Any of: <ul> <li> Upgrade to 4.2.7p11 or later. </li> <li> Follow BCP and put <code>restrict ... noquery</code> in your <code>ntp.conf</code> file. </li></ul> <p /> <h5><a name="Credit"></a> Credit </h5> This vulnerability was noticed in ntp-4.2.6 by Neel Mehta of the Google Security Team. <p /> <h4><a name="Non_cryptographic_random_number"></a> Non-cryptographic random number generator with weak seed used by <code>ntp-keygen</code> to generate symmetric keys. </h4> <p /> <ul> <li> References: [Sec 2666] / CVE-2014-9294 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:M/C:P/I:P/A:C) Base Score: 7.3 </li> <li> Vulnerable Versions: All NTP4 releases before 4.2.7p230 </li> <li> Date Resolved: Dev (4.2.7p230) 01 Nov 2011 </li></ul> <p /> <h5><a name="Summary_AN1"></a> Summary </h5> Prior to ntp-4.2.7p230 <code>ntp-keygen</code> used a weak seed to prepare a random number generator that was of good quality back in the late 1990s. The random numbers produced was then used to generate symmetric keys. In ntp-4.2.8 we use a current-technology cryptographic random number generator, either <code>RAND_bytes()</code> from OpenSSL, or <code>arc4random()</code>. <p /> <h5><a name="Mitigation_AN1"></a> Mitigation </h5> Any of: <ul> <li> Upgrade to 4.2.7p230 or later. </li> <li> Follow BCP and put <code>restrict ... noquery</code> in your <code>ntp.conf</code> file. </li></ul> <p /> <h5><a name="Credit_AN1"></a> Credit </h5> This vulnerability was discovered in ntp-4.2.6 by Stephen Roettger of the Google Security Team. <p /> <h4><a name="Buffer_overflow_in_crypto_recv"></a> Buffer overflow in <code>crypto_recv()</code> </h4> <p /> <ul> <li> References: Sec 2667 / CVE-2014-9295 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:N/C:P/I:P/A:P) Base Score: 7.5 </li> <li> Versions: All releases before 4.2.8 </li> <li> Date Resolved: Stable (4.2.8) 18 Dec 2014 </li></ul> <p /> <h5><a name="Summary_AN2"></a> Summary </h5> When Autokey Authentication is enabled (i.e. the <code>ntp.conf</code> file contains a 'crypto pw ...' directive) a remote attacker can send a carefully crafted packet that can overflow a stack buffer and potentially allow malicious code to be executed with the privilege level of the <code>ntpd</code> process. <p /> <h5><a name="Mitigation_AN2"></a> Mitigation </h5> Any of: <ul> <li> Upgrade to 4.2.8, or later, or </li> <li> Disable Autokey Authentication by removing or commenting out all configuration directives beginning with the <code>crypto</code> keyword in your <code>ntp.conf</code> file. </li></ul> <p /> <h5><a name="Credit_AN2"></a> Credit </h5> This vulnerability was discovered by Stephen Roettger of the Google Security Team. <p /> <h4><a name="Buffer_overflow_in_ctl_putdata"></a> Buffer overflow in <code>ctl_putdata()</code> </h4> <p /> <ul> <li> References: Sec 2668 / CVE-2014-9295 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:N/C:P/I:P/A:P) Base Score: 7.5 </li> <li> Versions: All NTP4 releases before 4.2.8 </li> <li> Date Resolved: Stable (4.2.8) 18 Dec 2014 </li></ul> <p /> <h5><a name="Summary_AN3"></a> Summary </h5> A remote attacker can send a carefully crafted packet that can overflow a stack buffer and potentially allow malicious code to be executed with the privilege level of the ntpd process. <p /> <h5><a name="Mitigation_AN3"></a> Mitigation </h5> Any of: <ul> <li> Upgrade to 4.2.8, or later. </li> <li> Follow BCP and put <code>restrict ... noquery</code> in your <code>ntp.conf</code> file. </li></ul> <p /> <h5><a name="Credit_AN3"></a> Credit </h5> This vulnerability was discovered by Stephen Roettger of the Google Security Team. <p /> <h4><a name="Buffer_overflow_in_configure"></a> Buffer overflow in <code>configure()</code> </h4> <p /> <ul> <li> References: Sec 2669 / CVE-2014-9295 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:N/C:P/I:P/A:P) Base Score: 7.5 </li> <li> Versions: All NTP4 releases before 4.2.8 </li> <li> Date Resolved: Stable (4.2.8) 18 Dec 2014 </li></ul> <p /> <h5><a name="Summary_AN4"></a> Summary </h5> A remote attacker can send a carefully crafted packet that can overflow a stack buffer and potentially allow malicious code to be executed with the privilege level of the <code>ntpd</code> process. <p /> <h5><a name="Mitigation_AN4"></a> Mitigation </h5> Any of: <ul> <li> Upgrade to 4.2.8, or later. </li> <li> Follow BCP and put <code>restrict ... noquery</code> in your <code>ntp.conf</code> file. </li></ul> <p /> <h5><a name="Credit_AN4"></a> Credit </h5> This vulnerability was discovered by Stephen Roettger of the Google Security Team. <p /> <h4><a name="receive_missing_return_on_error"></a> <code>receive()</code> missing return on error </h4> <p /> <ul> <li> References: Sec 2670 / CVE-2014-9296 / VU#852879 </li> <li> CVSS: (AV:N/AC:L/Au:N/C:N/I:N/A:P) Base Score: 5.0 </li> <li> Versions: All NTP4 releases before 4.2.8 </li> <li> Date Resolved: Stable (4.2.8) 18 Dec 2014 </li></ul> <p /> <h5><a name="Summary_AN5"></a> Summary </h5> Code in <code>ntp_proto.c:receive()</code> was missing a <code>return;</code> in the code path where an error was detected, which meant processing did not stop when a specific rare error occurred. We haven't found a way for this bug to affect system integrity. If there is no way to affect system integrity the base CVSS score for this bug is 0. If there is one avenue through which system integrity can be partially affected, the base score becomes a 5. If system integrity can be partially affected via all three integrity metrics, the CVSS base score become 7.5. <p /> <h5><a name="Mitigation_AN5"></a> Mitigation </h5> Any of: * Upgrade to 4.2.8, or later. * Remove or comment out all configuration directives beginning with the crypto keyword in your <code>ntp.conf</code> file. <p /> <h5><a name="Credit_AN5"></a> Credit </h5> This vulnerability was discovered by Stephen Roettger of the Google Security Team. <p /> See <a href="http://support.ntp.org/security" rel="nofollow" target="_top">http://support.ntp.org/security</a> for more information. <p /> <h4><a name="New_features_changes_in_this_rel"></a> New features / changes in this release: </h4> <p /> <h5><a name="Important_Changes"></a> Important Changes </h5> <p /> <h6><a name="Internal_NTP_Era_counters"></a> Internal NTP Era counters </h6> <p /> The internal counters that track the "era" (range of years) we are in rolls over every 136 years'. The current "era" started at the stroke of midnight on 1 Jan 1900, and ends just before the stroke of midnight on 1 Jan 2036. <p /> In the past, we have used the "midpoint" of the range to decide which era we were in. Given the longevity of some products, it became clear that it would be more functional to "look back" less, and "look forward" more. We now compile a timestamp into the ntpd executable and when we get a timestamp we us the "built-on" to tell us what era we are in. This check "looks back" 10 years, and "looks forward" 126 years. <p /> <h6><a name="ntpdc_responses_disabled_by_defa"></a> <code>ntpdc</code> responses disabled by default </h6> <p /> Dave Hart writes: <p /> For a long time, <code>ntpq</code> and its mostly text-based mode 6 (control) protocol have been preferred over <code>ntpdc</code> and its mode 7 (private request) protocol for runtime queries and configuration. There has been a goal of deprecating <code>ntpdc</code>, previously held back by numerous capabilities exposed by <code>ntpdc</code> with no <code>ntpq</code> equivalent. I have been adding commands to <code>ntpq</code> to cover these cases, and I believe I've covered them all, though I've not compared command-by-command recently. <p /> As I've said previously, the binary mode 7 protocol involves a lot of hand-rolled structure layout and byte-swapping code in both <code>ntpd</code> and <code>ntpdc</code> which is hard to get right. As <code>ntpd</code> grows and changes, the changes are difficult to expose via <code>ntpdc</code> while maintaining forward and backward compatibility between <code>ntpdc</code> and <code>ntpd</code>. In contrast, <code>ntpq='s text-based, =label=value</code> approach involves more code reuse and allows compatible changes without extra work in most cases. <p /> Mode 7 has always been defined as vendor/implementation-specific while mode 6 is described in RFC 1305 and intended to be open to interoperate with other implementations. There is an early draft of an updated mode 6 description that likely will join the other NTPv4 RFCs eventually. (<a href="http://tools.ietf.org/html/draft-odonoghue-ntpv4-control-01" rel="nofollow" target="_top">http://tools.ietf.org/html/draft-odonoghue-ntpv4-control-01</a>) <p /> For these reasons, ntpd 4.2.7p230 by default disables processing of <code>ntpdc</code> queries, reducing =ntpd='s attack surface and functionally deprecating <code>ntpdc</code>. If you are in the habit of using <code>ntpdc</code> for certain operations, please try the <code>ntpq</code> equivalent. If there's no equivalent, please open a bug report at <a href="http://bugs.ntp.org./" rel="nofollow" target="_top">http://bugs.ntp.org./</a> <p /> In addition to the above, over 1100 issues have been resolved between the 4.2.6 branch and 4.2.8.
