CVE-2014-9293

TITLE

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

DESCRIPTION

The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. 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. Supplementary information : CWE Vulnerability types by CWE-332: Insufficient Entropy in PRNG (PRNG Insufficient entropy in ) Has been identified. http://cwe.mitre.org/data/definitions/332.htmlBrute force attack by a third party (Brute force attack) Could be used to break cryptographic protection mechanisms. NTP is prone to a security weakness. An attacker can exploit this issue to guess the generated key, and possibly use it to send an ntpdc query or configuration requests. Network Time Protocol is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Successful exploits may allow an attacker to execute arbitrary code with the privileges of the ntpd process. Failed attempts will likely cause a denial-of-service condition. Network Time Protocol 4.2.7 and prior are vulnerable. 6.5) - i386, noarch, ppc64, s390x, x86_64 3. Release Date: 2015-02-18 Last Updated: 2015-02-18 Potential Security Impact: Remote execution of code, Denial of Service (DoS), or other vulnerabilities Source: Hewlett-Packard Company, HP Software Security Response Team VULNERABILITY SUMMARY Potential security vulnerabilities have been identified with HP-UX running NTP. These could be exploited remotely to execute code, create a Denial of Service (DoS), or other vulnerabilities.

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-2014-9293) It was found that ntp-keygen used a weak method for generating MD5 keys. 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.

The two patches are available from the HP Support Center (HPSC). Reference: http://support.ntp.org/bin/view/Main/SecurityNotice MANUAL ACTIONS: Yes - Update If patch installation on B.11.11 or B.11.23 is not possible, mitigate with step above. A remote unauthenticated attacker may craft special packets that trigger buffer overflows in the ntpd functions crypto_recv() (when using autokey authentication), ctl_putdata(), and configure(). A section of code in ntpd handling a rare error is missing a return statement, therefore processing did not stop when the error was encountered. 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.

The default compiler options for affected releases should reduce the vulnerability to a denial of service. In addition, attackers would be isolated by the NTP AppArmor profile. (CVE-2014-9295) Stephen Roettger discovered that NTP incorrectly continued processing when handling certain errors. (CVE-2014-9296) 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-3ubuntu2.14.10.1 Ubuntu 14.04 LTS: ntp 1:4.2.6.p5+dfsg-3ubuntu2.14.04.1 Ubuntu 12.04 LTS: ntp 1:4.2.6.p3+dfsg-1ubuntu3.2 Ubuntu 10.04 LTS: ntp 1:4.2.4p8+dfsg-1ubuntu2.2 After a standard system update you need to regenerate any MD5 keys that were manually created with ntp-keygen
