CVE-2014-9296

TITLE

NTP Project Network Time Protocol daemon (ntpd) contains multiple vulnerabilities (Updated)

DESCRIPTION

The receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets. The NTP Project ntpd version 4.2.7 and pervious versions contain several vulnerabilities. ntp-keygen prior to version 4.2.7p230 also uses a non-cryptographic random number generator when generating symmetric keys. These vulnerabilities may affect ntpd acting as a server or client. Network Time Protocol is prone to an unspecified security vulnerability. Little is known about this issue or its effects at this time. We will update this BID as more information emerges. Network Time Protocol 4.2.7 is vulnerable; other versions may also be affected. Corrected: 2014-14-22 19:07:16 UTC (stable/10, 10.1-STABLE) 2014-12-23 22:56:01 UTC (releng/10.1, 10.1-RELEASE-p3) 2014-12-23 22:55:14 UTC (releng/10.0, 10.0-RELEASE-p15) 2014-14-22 19:08:09 UTC (stable/9, 9.3-STABLE) 2014-12-23 22:54:25 UTC (releng/9.3, 9.3-RELEASE-p7) 2014-12-23 22:53:44 UTC (releng/9.2, 9.2-RELEASE-p17) 2014-12-23 22:53:03 UTC (releng/9.1, 9.1-RELEASE-p24) 2014-14-22 19:08:09 UTC (stable/8, 8.4-STABLE) 2014-12-23 22:52:22 UTC (releng/8.4, 8.4-RELEASE-p21) CVE Name: CVE-2014-9293, CVE-2014-9294, CVE-2014-9295, CVE-2014-9296 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. II. [CVE-2014-9293] The ntp-keygen(8) utility is also affected by a similar issue. [CVE-2014-9294] When Autokey Authentication is enabled, for example if ntp.conf(5) contains a 'crypto pw' directive, a remote attacker can send a carefully crafted packet that can overflow a stack buffer. [CVE-2014-9296] III. Impact The NTP protocol uses keys to implement authentication. The weak seeding of the pseudo-random number generator makes it easier for an attacker to brute-force keys, and thus may broadcast incorrect time stamps or masquerade as another time server. [CVE-2014-9295] IV. Workaround No workaround is available, but systems not running ntpd(8) are not affected. Because the issue may lead to remote root compromise, the FreeBSD Security Team recommends system administrators to firewall NTP ports, namely tcp/123 and udp/123 when it is not clear that all systems have been patched or have ntpd(8) stopped. V. Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/SA-14:31/ntp.patch # fetch https://security.FreeBSD.org/patches/SA-14:31/ntp.patch.asc # gpg --verify ntp.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>. Restart the ntpd(8) daemons, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch.

Summary: Updated ntp packages that fix several security issues are now available for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, x86_64 3. Multiple buffer overflow flaws were discovered in ntpd's crypto_recv(), ctl_putdata(), and configure() functions. Note: the crypto_recv() flaw requires non-default configurations to be active, while the ctl_putdata() flaw, by default, can only be exploited via local attackers, and the configure() flaw requires additional authentication to exploit. (CVE-2014-9295) It was found that ntpd automatically generated weak keys for its internal use if no ntpdc request authentication key was specified in the ntp.conf configuration file. A remote attacker able to match the configured IP restrictions could guess the generated key, and possibly use it to send ntpdc query or configuration requests. (CVE-2014-9293) It was found that ntp-keygen used a weak method for generating MD5 keys. This could possibly allow an attacker to guess generated MD5 keys that could then be used to spoof an NTP client or server. Note: it is recommended to regenerate any MD5 keys that had explicitly been generated with ntp-keygen; the default installation does not contain such keys). (CVE-2014-9294) A missing return statement in the receive() function could potentially allow a remote attacker to bypass NTP's authentication mechanism. (CVE-2014-9296) All ntp users are advised to upgrade to this updated package, which contains backported patches to resolve these issues. After installing the update, the ntpd daemon will restart automatically. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.

On December 19, 2014, NTP.org and US-CERT released security advisories detailing two issues regarding weak cryptographic pseudorandom number generation (PRNG), three buffer overflow vulnerabilities, and an unhandled error condition with an unknown impact. Cisco will release free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available. This situation may be exploitable by an attacker (CVE-2014-9296). Stephen Roettger of the Google Security Team, Sebastian Krahmer of the SUSE Security Team and Harlan Stenn of Network Time Foundation discovered that the length value in extension fields is not properly validated in several code paths in ntp_crypto.c, which could lead to information leakage or denial of service (CVE-2014-9297). Stephen Roettger of the Google Security Team reported that ACLs based on IPv6 ::1 (localhost) addresses can be bypassed (CVE-2014-9298). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9293 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9294 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9295 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9296 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9297 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9298 http://advisories.mageia.org/MGASA-2014-0541.html http://advisories.mageia.org/MGASA-2015-0063.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 8f7d14b95c55bd1de7230cff0c8ea9d7 mbs2/x86_64/ntp-4.2.6p5-16.1.mbs2.x86_64.rpm 09063ab11459b1f935809b37c742ff12 mbs2/x86_64/ntp-client-4.2.6p5-16.1.mbs2.x86_64.rpm 7a0d0eca35911d9f15b76b474c5512cf mbs2/x86_64/ntp-doc-4.2.6p5-16.1.mbs2.noarch.rpm cb0371050702950084ff633ea45c2c5c mbs2/SRPMS/ntp-4.2.6p5-16.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
