1NTP 4.2.4p8 (Harlan Stenn <firstname.lastname@example.org>, 2009/12/08) 2 3Focus: Security Fixes 4 5Severity: HIGH 6 7This release fixes the following high-severity vulnerability: 8 9* [Sec 1331] DoS with mode 7 packets - CVE-2009-3563. 10 11 See http://support.ntp.org/security for more information. 12 13 NTP mode 7 (MODE_PRIVATE) is used by the ntpdc query and control utility. 14 In contrast, ntpq uses NTP mode 6 (MODE_CONTROL), while routine NTP time 15 transfers use modes 1 through 5. Upon receipt of an incorrect mode 7 16 request or a mode 7 error response from an address which is not listed 17 in a "restrict ... noquery" or "restrict ... ignore" statement, ntpd will 18 reply with a mode 7 error response (and log a message). In this case: 19 20 * If an attacker spoofs the source address of ntpd host A in a 21 mode 7 response packet sent to ntpd host B, both A and B will 22 continuously send each other error responses, for as long as 23 those packets get through. 24 25 * If an attacker spoofs an address of ntpd host A in a mode 7 26 response packet sent to ntpd host A, A will respond to itself 27 endlessly, consuming CPU and logging excessively. 28 29 Credit for finding this vulnerability goes to Robin Park and Dmitri 30 Vinokurov of Alcatel-Lucent. 31 32THIS IS A STRONGLY RECOMMENDED UPGRADE. 33 34--- 35NTP 4.2.4p7 (Harlan Stenn <email@example.com>, 2009/05/04) 36 37Focus: Security and Bug Fixes 38 39Severity: HIGH 40 41This release fixes the following high-severity vulnerability: 42 43* [Sec 1151] Remote exploit if autokey is enabled. CVE-2009-1252 44 45 See http://support.ntp.org/security for more information. 46 47 If autokey is enabled (if ntp.conf contains a "crypto pw whatever" 48 line) then a carefully crafted packet sent to the machine will cause 49 a buffer overflow and possible execution of injected code, running 50 with the privileges of the ntpd process (often root). 51 52 Credit for finding this vulnerability goes to Chris Ries of CMU. 53 54This release fixes the following low-severity vulnerabilities: 55 56* [Sec 1144] limited (two byte) buffer overflow in ntpq. CVE-2009-0159 57 Credit for finding this vulnerability goes to Geoff Keating of Apple. 58 59* [Sec 1149] use SO_EXCLUSIVEADDRUSE on Windows 60 Credit for finding this issue goes to Dave Hart. 61 62This release fixes a number of bugs and adds some improvements: 63 64* Improved logging 65* Fix many compiler warnings 66* Many fixes and improvements for Windows 67* Adds support for AIX 6.1 68* Resolves some issues under MacOS X and Solaris 69 70THIS IS A STRONGLY RECOMMENDED UPGRADE. 71 72--- 73NTP 4.2.4p6 (Harlan Stenn <firstname.lastname@example.org>, 2009/01/07) 74 75Focus: Security Fix 76 77Severity: Low 78 79This release fixes oCERT.org's CVE-2009-0021, a vulnerability affecting 80the OpenSSL library relating to the incorrect checking of the return 81value of EVP_VerifyFinal function. 82 83Credit for finding this issue goes to the Google Security Team for 84finding the original issue with OpenSSL, and to ocert.org for finding 85the problem in NTP and telling us about it. 86 87This is a recommended upgrade. 88--- 89NTP 4.2.4p5 (Harlan Stenn <email@example.com>, 2008/08/17) 90 91Focus: Minor Bugfixes 92 93This release fixes a number of Windows-specific ntpd bugs and 94platform-independent ntpdate bugs. A logging bugfix has been applied 95to the ONCORE driver. 96 97The "dynamic" keyword and is now obsolete and deferred binding to local 98interfaces is the new default. The minimum time restriction for the 99interface update interval has been dropped. 100 101A number of minor build system and documentation fixes are included. 102 103This is a recommended upgrade for Windows. 104 105--- 106NTP 4.2.4p4 (Harlan Stenn <firstname.lastname@example.org>, 2007/09/10) 107 108Focus: Minor Bugfixes 109 110This release updates certain copyright information, fixes several display 111bugs in ntpdc, avoids SIGIO interrupting malloc(), cleans up file descriptor 112shutdown in the parse refclock driver, removes some lint from the code, 113stops accessing certain buffers immediately after they were freed, fixes 114a problem with non-command-line specification of -6, and allows the loopback 115interface to share addresses with other interfaces. 116 117--- 118NTP 4.2.4p3 (Harlan Stenn <email@example.com>, 2007/06/29) 119 120Focus: Minor Bugfixes 121 122This release fixes a bug in Windows that made it difficult to 123terminate ntpd under windows. 124This is a recommended upgrade for Windows. 125 126--- 127NTP 4.2.4p2 (Harlan Stenn <firstname.lastname@example.org>, 2007/06/19) 128 129Focus: Minor Bugfixes 130 131This release fixes a multicast mode authentication problem, 132an error in NTP packet handling on Windows that could lead to 133ntpd crashing, and several other minor bugs. Handling of 134multicast interfaces and logging configuration were improved. 135The required versions of autogen and libopts were incremented. 136This is a recommended upgrade for Windows and multicast users. 137 138--- 139NTP 4.2.4 (Harlan Stenn <email@example.com>, 2006/12/31) 140 141Focus: enhancements and bug fixes. 142 143Dynamic interface rescanning was added to simplify the use of ntpd in 144conjunction with DHCP. GNU AutoGen is used for its command-line options 145processing. Separate PPS devices are supported for PARSE refclocks, MD5 146signatures are now provided for the release files. Drivers have been 147added for some new ref-clocks and have been removed for some older 148ref-clocks. This release also includes other improvements, documentation 149and bug fixes. 150 151K&R C is no longer supported as of NTP-4.2.4. We are now aiming for ANSI 152C support. 153 154--- 155NTP 4.2.0 (Harlan Stenn <firstname.lastname@example.org>, 2003/10/15) 156 157Focus: enhancements and bug fixes.
