CVE-2014-9295

TITLE

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

DESCRIPTION

Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to (1) the crypto_recv function when the Autokey Authentication feature is used, (2) the ctl_putdata function, and (3) the configure function. 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 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. 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-2014-9296] 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. Branch/path Revision - ------------------------------------------------------------------------- stable/8/ r276073 releng/8.4/ r276154 stable/9/ r276073 releng/9.1/ r276155 releng/9.2/ r276156 releng/9.3/ r276157 stable/10/ r276072 releng/10.0/ r276158 releng/10.1/ r276159 - ------------------------------------------------------------------------- To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: <URL:https://svnweb.freebsd.org/base?view=revision&revision=NNNNNN> VII.

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.
