NTP 4.2.4p8 (Harlan Stenn <stenn@ntp.org>, 2009/12/08)
|
|
|
|
Focus: Security Fixes
|
|
|
|
Severity: HIGH
|
|
|
|
This release fixes the following high-severity vulnerability:
|
|
|
|
* [Sec 1331] DoS with mode 7 packets - CVE-2009-3563.
|
|
|
|
See http://support.ntp.org/security for more information.
|
|
|
|
NTP mode 7 (MODE_PRIVATE) is used by the ntpdc query and control utility.
|
|
In contrast, ntpq uses NTP mode 6 (MODE_CONTROL), while routine NTP time
|
|
transfers use modes 1 through 5. Upon receipt of an incorrect mode 7
|
|
request or a mode 7 error response from an address which is not listed
|
|
in a "restrict ... noquery" or "restrict ... ignore" statement, ntpd will
|
|
reply with a mode 7 error response (and log a message). In this case:
|
|
|
|
* If an attacker spoofs the source address of ntpd host A in a
|
|
mode 7 response packet sent to ntpd host B, both A and B will
|
|
continuously send each other error responses, for as long as
|
|
those packets get through.
|
|
|
|
* If an attacker spoofs an address of ntpd host A in a mode 7
|
|
response packet sent to ntpd host A, A will respond to itself
|
|
endlessly, consuming CPU and logging excessively.
|
|
|
|
Credit for finding this vulnerability goes to Robin Park and Dmitri
|
|
Vinokurov of Alcatel-Lucent.
|
|
|
|
THIS IS A STRONGLY RECOMMENDED UPGRADE.

NTP 4.2.4p7 (Harlan Stenn <stenn@ntp.org>, 2009/05/04)
|
|
|
|
Focus: Security and Bug Fixes
|
|
|
|
Severity: HIGH
|
|
|
|
This release fixes the following high-severity vulnerability:
|
|
|
|
* [Sec 1151] Remote exploit if autokey is enabled. CVE-2009-1252
|
|
|
|
See http://support.ntp.org/security for more information.
|
|
|
|
If autokey is enabled (if ntp.conf contains a "crypto pw whatever"
|
|
line) then a carefully crafted packet sent to the machine will cause
|
|
a buffer overflow and possible execution of injected code, running
|
|
with the privileges of the ntpd process (often root).
|
|
|
|
Credit for finding this vulnerability goes to Chris Ries of CMU.
|
|
|
|
This release fixes the following low-severity vulnerabilities:
|
|
|
|
* [Sec 1144] limited (two byte) buffer overflow in ntpq. CVE-2009-0159
|
|
Credit for finding this vulnerability goes to Geoff Keating of Apple.
|
|
|
|
* [Sec 1149] use SO_EXCLUSIVEADDRUSE on Windows
|
|
Credit for finding this issue goes to Dave Hart.
|
|
|
|
This release fixes a number of bugs and adds some improvements:
|
|
|
|
* Improved logging
|
|
* Fix many compiler warnings
|
|
* Many fixes and improvements for Windows
|
|
* Adds support for AIX 6.1
|
|
* Resolves some issues under MacOS X and Solaris
|
|
|
|
THIS IS A STRONGLY RECOMMENDED UPGRADE.

NTP 4.2.4p6 (Harlan Stenn <stenn@ntp.org>, 2009/01/07)
|
|
|
|
Focus: Security Fix
|
|
|
|
Severity: Low
|
|
|
|
This release fixes oCERT.org's CVE-2009-0021, a vulnerability affecting
|
|
the OpenSSL library relating to the incorrect checking of the return
|
|
value of EVP_VerifyFinal function.
|
|
|
|
Credit for finding this issue goes to the Google Security Team for
|
|
finding the original issue with OpenSSL, and to ocert.org for finding
|
|
the problem in NTP and telling us about it.
|
|
|
|
This is a recommended upgrade.

NTP 4.2.4p5 (Harlan Stenn <stenn@ntp.org>, 2008/08/17)
|
|
|
|
Focus: Minor Bugfixes
|
|
|
|
This release fixes a number of Windows-specific ntpd bugs and
|
|
platform-independent ntpdate bugs. A logging bugfix has been applied
|
|
to the ONCORE driver.
|
|
|
|
The "dynamic" keyword and is now obsolete and deferred binding to local
|
|
interfaces is the new default. The minimum time restriction for the
|
|
interface update interval has been dropped.
|
|
|
|
A number of minor build system and documentation fixes are included.
|
|
|
|
This is a recommended upgrade for Windows.

NTP 4.2.4p4 (Harlan Stenn <stenn@ntp.org>, 2007/09/10)
|
|
|
|
Focus: Minor Bugfixes
|
|
|
|
This release updates certain copyright information, fixes several display
|
|
bugs in ntpdc, avoids SIGIO interrupting malloc(), cleans up file descriptor
|
|
shutdown in the parse refclock driver, removes some lint from the code,
|
|
stops accessing certain buffers immediately after they were freed, fixes
|
|
a problem with non-command-line specification of -6, and allows the loopback
|
|
interface to share addresses with other interfaces.

|
|
This release fixes a bug in Windows that made it difficult to
|
|
terminate ntpd under windows.

NTP 4.2.4p2 (Harlan Stenn <stenn@ntp.org>, 2007/06/19)
|
|
|
|
Focus: Minor Bugfixes
|
|
|
|
This release fixes a multicast mode authentication problem,
|
|
an error in NTP packet handling on Windows that could lead to
|
|
ntpd crashing, and several other minor bugs. Handling of
|
|
multicast interfaces and logging configuration were improved.
|
|
The required versions of autogen and libopts were incremented.
|
|
This is a recommended upgrade for Windows and multicast users.

NTP 4.2.4 (Harlan Stenn <stenn@ntp.org>, 2006/12/31)
|
|
|
|
Focus: enhancements and bug fixes.
|
|
|
|
Dynamic interface rescanning was added to simplify the use of ntpd in
|
|
conjunction with DHCP. GNU AutoGen is used for its command-line options
|
|
processing. Separate PPS devices are supported for PARSE refclocks, MD5
|
|
signatures are now provided for the release files. Drivers have been
|
|
added for some new ref-clocks and have been removed for some older
|
|
ref-clocks. This release also includes other improvements, documentation
|
|
and bug fixes.
|
|
|
|
K&R C is no longer supported as of NTP-4.2.4. We are now aiming for ANSI
|
|
C support.
