CVE-2015-1799

TITLE

NTP Project ntpd reference implementation contains multiple vulnerabilities

DESCRIPTION

The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer. NTP Project ntpd reference implementation accepts unauthenticated packets with symmetric key cryptography and does not protect symmetric associations against denial of service attacks. NTP of ntpd of ntp_proto.c Inside receive of symmetric-key The function is used even when a specific invalid packet is received. state variable Service operation disruption to perform update ( Sync failure ) There are vulnerabilities that are put into a state. Supplementary information : CWE Vulnerability type by CWE-17: Code ( code ) Has been identified. http://cwe.mitre.org/data/definitions/17.htmlMan-in-the-middle attacks (man-in-the-middle attack) By the source of the peer IP Denial of service by spoofing addresses ( Sync failure ) There is a possibility of being put into a state. NTP is prone to a denial-of-service vulnerability. Successful exploits may allow the attacker to cause a denial-of-service condition. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201509-01 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: NTP: Multiple vulnerablities Date: September 24, 2015 Bugs: #545836, #553682 ID: 201509-01 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in NTP, the worst of which could lead to arbitrary code execution.

Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP. This issue could either cause ntp-keygen to hang, or could result in non-random keys. (CVE number pending) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: ntp 1:4.2.6.p5+dfsg-3ubuntu2.14.10.3 Ubuntu 14.04 LTS: ntp 1:4.2.6.p5+dfsg-3ubuntu2.14.04.3 Ubuntu 12.04 LTS: ntp 1:4.2.6.p3+dfsg-1ubuntu3.4 In general, a standard system update will make all the necessary changes. 7) - noarch, x86_64 3. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service. (BZ#1191111) * The ntpd service could previously join multicast groups only when starting, which caused problems if ntpd was started during system boot before network was configured. With this update, ntpd attempts to join multicast groups every time network configuration is changed. (BZ#1171640) Enhancements: * This update adds support for configurable Differentiated Services Code Points (DSCP) in NTP packets, simplifying configuration in large networks where different NTP implementations or versions are using different DSCP values. (BZ#1202828) * This update adds the ability to configure separate clock stepping thresholds for each direction (backward and forward). Use the "stepback" and "stepfwd" options to configure each threshold. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: ntp security, bug fix, and enhancement update Advisory ID: RHSA-2015:1459-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1459.html Issue date: 2015-07-22 Updated on: 2015-02-25 CVE Names: CVE-2014-9297 CVE-2014-9298 CVE-2015-1798 CVE-2015-1799 CVE-2015-3405 ===================================================================== 1.

Description: The Network Time Protocol (NTP) is used to synchronize a computer's time with another referenced time source. It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by spoofing ::1 addresses. (CVE-2014-9298) A denial of service flaw was found in the way NTP hosts that were peering with each other authenticated themselves before updating their internal state variables. An attacker could send packets to one peer host, which could cascade to other peers, and stop the synchronization process among the reached peers. (CVE-2015-1799) A flaw was found in the way the ntp-keygen utility generated MD5 symmetric keys on big-endian systems. An attacker could possibly use this flaw to guess generated MD5 keys, which could then be used to spoof an NTP client or server. (CVE-2015-3405) A stack-based buffer overflow was found in the way the NTP autokey protocol was implemented. When an NTP client decrypted a secret received from an NTP server, it could cause that client to crash. (CVE-2014-9297) It was found that ntpd did not check whether a Message Authentication Code (MAC) was present in a received packet when ntpd was configured to use symmetric cryptographic keys. A man-in-the-middle attacker could use this flaw to send crafted packets that would be accepted by a client or a peer without the attacker knowing the symmetric key. (CVE-2015-1798) The CVE-2015-1798 and CVE-2015-1799 issues were discovered by Miroslav Lichvár of Red Hat. Bug fixes: * The ntpd daemon truncated symmetric keys specified in the key file to 20 bytes. As a consequence, it was impossible to configure NTP authentication to work with peers that use longer keys. The maximum length of keys has now been changed to 32 bytes. (BZ#1053551) * The ntp-keygen utility used the exponent of 3 when generating RSA keys, and generating RSA keys failed when FIPS mode was enabled. ntp-keygen has been modified to use the exponent of 65537, and generating keys in FIPS mode now works as expected. (BZ#1184421) * The ntpd daemon included a root delay when calculating its root dispersion. Consequently, the NTP server reported larger root dispersion than it should have and clients could reject the source when its distance reached the maximum synchronization distance (1.5 seconds by default). Calculation of root dispersion has been fixed, the root dispersion is now reported correctly, and clients no longer reject the server due to a large synchronization distance. (BZ#1045376) * The ntpd daemon dropped incoming NTP packets if their source port was lower than 123 (the NTP port). Clients behind Network Address Translation (NAT) were unable to synchronize with the server if their source port was translated to ports below 123. With this update, ntpd no longer checks the source port number. (BZ#1171630) Enhancements: * This update introduces configurable access of memory segments used for Shared Memory Driver (SHM) reference clocks. Previously, only the first two memory segments were created with owner-only access, allowing just two SHM reference clocks to be used securely on a system. Now, the owner-only access to SHM is configurable with the "mode" option, and it is therefore possible to use more SHM reference clocks securely. (BZ#1122015) * Support for nanosecond resolution has been added to the SHM reference clock. Prior to this update, when a Precision Time Protocol (PTP) hardware clock was used as a time source to synchronize the system clock (for example, with the timemaster service from the linuxptp package), the accuracy of the synchronization was limited due to the microsecond resolution of the SHM protocol. The nanosecond extension in the SHM protocol now enables sub-microsecond synchronization of the system clock. (BZ#1117704) 4. Solution: All ntp users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. After installing the update, the ntpd daemon will restart automatically. Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 995134 - ntp package doesn't build with net-snmp-devel 1045376 - Fix root distance and root dispersion calculations.
