NTP 4.2.8p6
Focus: Security, Bug fixes, enhancements.
Severity: MEDIUM
In addition to bug fixes and enhancements, this release fixes the
following X low- and Y medium-severity vulnerabilities:
* Potential Infinite Loop in 'ntpq'
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2548 / CVE-2015-8158
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS2: (AV:N/AC:M/Au:N/C:N/I:N/A:P) Base Score: 4.3 - MEDIUM
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N Base Score: 5.3 - MEDIUM
Summary: 'ntpq' processes incoming packets in a loop in 'getresponse()'.
The loop's only stopping conditions are receiving a complete and
correct response or hitting a small number of error conditions.
If the packet contains incorrect values that don't trigger one of
the error conditions, the loop continues to receive new packets.
Note well, this is an attack against an instance of 'ntpq', not
'ntpd', and this attack requires the attacker to do one of the
following:
* Own a malicious NTP server that the client trusts
* Prevent a legitimate NTP server from sending packets to
the 'ntpq' client
* MITM the 'ntpq' communications between the 'ntpq' client
and the NTP server
Mitigation:
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page
Credit: This weakness was discovered by Jonathan Gardner of Cisco ASIG.
* 0rigin: Zero Origin Timestamp Bypass
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2945 / CVE-2015-8138
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS2: (AV:N/AC:L/Au:N/C:N/I:P/A:N) Base Score: 5.0 - MEDIUM
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N Base Score: 5.3 - MEDIUM
(3.7 - LOW if you score AC:L)
Summary: To distinguish legitimate peer responses from forgeries, a
client attempts to verify a response packet by ensuring that the
origin timestamp in the packet matches the origin timestamp it
transmitted in its last request. A logic error exists that
allows packets with an origin timestamp of zero to bypass this
check whenever there is not an outstanding request to the server.
Mitigation:
Configure 'ntpd' to get time from multiple sources.
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page.
Monitor your 'ntpd= instances.
Credit: This weakness was discovered by Jonathan Gardner of Cisco ASIG.
* Stack exhaustion in recursive traversal of restriction list
Date Resolved: Stable (4.2.8p6) 19 Jan 2016
References: Sec 2940 / CVE-2015-7978
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:N/AC:M/Au:N/C:N/I:N/A:P) Base Score: 4.3 - MEDIUM
Summary: An unauthenticated 'ntpdc reslist' command can cause a
segmentation fault in ntpd by exhausting the call stack.
Mitigation:
Implement BCP-38.
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page.
If you are unable to upgrade:
In ntp-4.2.8, mode 7 is disabled by default. Don't enable it.
If you must enable mode 7:
configure the use of a 'requestkey' to control who can
issue mode 7 requests.
configure 'restrict noquery' to further limit mode 7
requests to trusted sources.
Monitor your ntpd instances.
Credit: This weakness was discovered by Stephen Gray at Cisco ASIG.
* Off-path Denial of Service (!DoS) attack on authenticated broadcast mode
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2942 / CVE-2015-7979
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:N/AC:M/Au:N/C:N/I:P/A:P) Base Score: 5.8
Summary: An off-path attacker can send broadcast packets with bad
authentication (wrong key, mismatched key, incorrect MAC, etc)
to broadcast clients. It is observed that the broadcast client
tears down the association with the broadcast server upon
receiving just one bad packet.
Mitigation:
Implement BCP-38.
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page.
Monitor your 'ntpd' instances.
If this sort of attack is an active problem for you, you have
deeper problems to investigate. In this case also consider
having smaller NTP broadcast domains.
Credit: This weakness was discovered by Aanchal Malhotra of Boston
University.
* reslist NULL pointer dereference
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2939 / CVE-2015-7977
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:N/AC:M/Au:N/C:N/I:N/A:P) Base Score: 4.3 - MEDIUM
Summary: An unauthenticated 'ntpdc reslist' command can cause a
segmentation fault in ntpd by causing a NULL pointer dereference.
Mitigation:
Implement BCP-38.
Upgrade to 4.2.8p6, or later, from NTP Project Download Page or
the NTP Public Services Project Download Page.
If you are unable to upgrade:
mode 7 is disabled by default. Don't enable it.
If you must enable mode 7:
configure the use of a 'requestkey' to control who can
issue mode 7 requests.
configure 'restrict noquery' to further limit mode 7
requests to trusted sources.
Monitor your ntpd instances.
Credit: This weakness was discovered by Stephen Gray of Cisco ASIG.
* 'ntpq saveconfig' command allows dangerous characters in filenames.
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2938 / CVE-2015-7976
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:N/AC:L/Au:S/C:N/I:P/A:N) Base Score: 4.0 - MEDIUM
Summary: The ntpq saveconfig command does not do adequate filtering
of special characters from the supplied filename.
Note well: The ability to use the saveconfig command is controlled
by the 'restrict nomodify' directive, and the recommended default
configuration is to disable this capability. If the ability to
execute a 'saveconfig' is required, it can easily (and should) be
limited and restricted to a known small number of IP addresses.
Mitigation:
Implement BCP-38.
use 'restrict default nomodify' in your 'ntp.conf' file.
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page.
If you are unable to upgrade:
build NTP with 'configure --disable-saveconfig' if you will
never need this capability, or
use 'restrict default nomodify' in your 'ntp.conf' file. Be
careful about what IPs have the ability to send 'modify'
requests to 'ntpd'.
Monitor your ntpd instances.
'saveconfig' requests are logged to syslog - monitor your syslog files.
Credit: This weakness was discovered by Jonathan Gardner of Cisco ASIG.
* nextvar() missing length check in ntpq
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2937 / CVE-2015-7975
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:L/AC:H/Au:N/C:N/I:N/A:P) Base Score: 1.2 - LOW
If you score A:C, this becomes 4.0.
CVSSv3: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) Base Score 2.9, LOW
Summary: ntpq may call nextvar() which executes a memcpy() into the
name buffer without a proper length check against its maximum
length of 256 bytes. Note well that we're taking about ntpq here.
The usual worst-case effect of this vulnerability is that the
specific instance of ntpq will crash and the person or process
that did this will have stopped themselves.
Mitigation:
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page.
If you are unable to upgrade:
If you have scripts that feed input to ntpq make sure there are
some sanity checks on the input received from the "outside".
This is potentially more dangerous if ntpq is run as root.
Credit: This weakness was discovered by Jonathan Gardner at Cisco ASIG.
* Skeleton Key: Any trusted key system can serve time
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2936 / CVE-2015-7974
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:N/AC:H/Au:S/C:N/I:C/A:N) Base Score: 4.9
Summary: Symmetric key encryption uses a shared trusted key. The
reported title for this issue was "Missing key check allows
impersonation between authenticated peers" and the report claimed
"A key specified only for one server should only work to
authenticate that server, other trusted keys should be refused."
Except there has never been any correlation between this trusted
key and server v. clients machines and there has never been any
way to specify a key only for one server. We have treated this as
an enhancement request, and ntp-4.2.8p6 includes other checks and
tests to strengthen clients against attacks coming from broadcast
servers.
Mitigation:
Implement BCP-38.
If this scenario represents a real or a potential issue for you,
upgrade to 4.2.8p6, or later, from the NTP Project Download
Page or the NTP Public Services Project Download Page, and
use the new field in the ntp.keys file that specifies the list
of IPs that are allowed to serve time. Note that this alone
will not protect against time packets with forged source IP
addresses, however other changes in ntp-4.2.8p6 provide
significant mitigation against broadcast attacks. MITM attacks
are a different story.
If you are unable to upgrade:
Don't use broadcast mode if you cannot monitor your client
servers.
If you choose to use symmetric keys to authenticate time
packets in a hostile environment where ephemeral time
servers can be created, or if it is expected that malicious
time servers will participate in an NTP broadcast domain,
limit the number of participating systems that participate
in the shared-key group.
Monitor your ntpd instances.
Credit: This weakness was discovered by Matt Street of Cisco ASIG.
* Deja Vu: Replay attack on authenticated broadcast mode
Date Resolved: Stable (4.2.8p6) 19 Jan 2016; Dev (4.3.90) 19 Jan 2016
References: Sec 2935 / CVE-2015-7973
Affects: All ntp-4 releases up to, but not including 4.2.8p6, and
4.3.0 up to, but not including 4.3.90
CVSS: (AV:A/AC:M/Au:N/C:N/I:P/A:P) Base Score: 4.3 - MEDIUM
Summary: If an NTP network is configured for broadcast operations then
either a man-in-the-middle attacker or a malicious participant
that has the same trusted keys as the victim can replay time packets.
Mitigation:
Implement BCP-38.
Upgrade to 4.2.8p6, or later, from the NTP Project Download Page
or the NTP Public Services Project Download Page.
If you are unable to upgrade:
Don't use broadcast mode if you cannot monitor your client servers.
Monitor your ntpd instances.
Credit: This weakness was discovered by Aanchal Malhotra of Boston
University.
