An update that solves 43 vulnerabilities and has 9 fixes is
now available.

Description:


NTP was updated to version 4.2.8p8 to fix several security issues and to
ensure the continued maintainability of the package.

These security issues were fixed:

* CVE-2016-4953: Bad authentication demobilized ephemeral associations
(bsc#982065).
* CVE-2016-4954: Processing spoofed server packets (bsc#982066).

* CVE-2016-4957: CRYPTO_NAK crash (bsc#982064).
* CVE-2016-1547: Validate crypto-NAKs to prevent ACRYPTO-NAK DoS
(bsc#977459).
* CVE-2016-1548: Prevent the change of time of an ntpd client or
denying service to an ntpd client by forcing it to change from basic
client/server mode to interleaved symmetric mode (bsc#977461).
* CVE-2016-1549: Sybil vulnerability: ephemeral association attack
(bsc#977451).
* CVE-2016-1550: Improve security against buffer comparison timing
attacks (bsc#977464).
* CVE-2016-1551: Refclock impersonation vulnerability (bsc#977450)y
* CVE-2016-2516: Duplicate IPs on unconfig directives could have
caused an assertion botch in ntpd (bsc#977452).
* CVE-2016-2517: Remote configuration trustedkey/
requestkey/controlkey values are not properly validated (bsc#977455).
* CVE-2016-2518: Crafted addpeer with hmode > 7 causes array
wraparound with MATCH_ASSOC (bsc#977457).
* CVE-2016-2519: ctl_getitem() return value not always checked
(bsc#977458).
* CVE-2015-8158: Potential Infinite Loop in ntpq (bsc#962966).
* CVE-2015-8138: Zero Origin Timestamp Bypass (bsc#963002).
* CVE-2015-7979: Off-path Denial of Service (DoS) attack on
authenticated broadcast mode (bsc#962784).
* CVE-2015-7978: Stack exhaustion in recursive traversal of
restriction list (bsc#963000).
* CVE-2015-7977: reslist NULL pointer dereference (bsc#962970).
* CVE-2015-7976: ntpq saveconfig command allowed dangerous characters
in filenames (bsc#962802).
* CVE-2015-7975: nextvar() missing length check (bsc#962988).
* CVE-2015-7974: NTP did not verify peer associations of symmetric
keys when authenticating packets, which might have allowed remote
attackers to conduct impersonation attacks via an arbitrary trusted
key, aka a "skeleton" key (bsc#962960).
* CVE-2015-7973: Replay attack on authenticated broadcast mode
(bsc#962995).
* CVE-2015-5300: MITM attacker can force ntpd to make a step larger
than the panic threshold (bsc#951629).
* CVE-2015-5194: Crash with crafted logconfig configuration command
(bsc#943218).
* CVE-2015-7871: NAK to the Future: Symmetric association
authentication bypass via crypto-NAK (bsc#952611).
* CVE-2015-7855: decodenetnum() will ASSERT botch instead of returning
FAIL on some bogus values (bsc#952611).
* CVE-2015-7854: Password Length Memory Corruption Vulnerability
(bsc#952611).
* CVE-2015-7853: Invalid length data provided by a custom refclock
driver could cause a buffer overflow (bsc#952611).
* CVE-2015-7852: ntpq atoascii() Memory Corruption Vulnerability
(bsc#952611).
* CVE-2015-7851: saveconfig Directory Traversal Vulnerability
(bsc#952611).
* CVE-2015-7850: Clients that receive a KoD now validate the origin
timestamp field (bsc#952611).
* CVE-2015-7849: Prevent use-after-free trusted key (bsc#952611).
* CVE-2015-7848: Prevent mode 7 loop counter underrun (bsc#952611).
* CVE-2015-7701: Slow memory leak in CRYPTO_ASSOC (bsc#952611).
* CVE-2015-7703: Configuration directives "pidfile" and
"driftfile"
should only be allowed locally (bsc#943221).
* CVE-2015-7704: Clients that receive a KoD should validate the origin
timestamp field (bsc#952611).
* CVE-2015-7705: Clients that receive a KoD should validate the origin
timestamp field (bsc#952611).
* CVE-2015-7691: Incomplete autokey data packet length checks
(bsc#952611).
* CVE-2015-7692: Incomplete autokey data packet length checks
(bsc#952611).
* CVE-2015-7702: Incomplete autokey data packet length checks
(bsc#952611).
* CVE-2015-1798: The symmetric-key feature in the receive function in
ntp_proto.c in ntpd in NTP required a correct MAC only if the MAC
field has a nonzero length, which made it easier for
man-in-the-middle attackers to spoof packets by omitting the MAC
(bsc#924202).
* CVE-2015-1799: The symmetric-key feature in the receive function in
ntp_proto.c in ntpd in NTP performed state-variable updates upon
receiving certain invalid packets, which made 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
(bsc#924202).

These non-security issues were fixed:

* Keep the parent process alive until the daemon has finished
initialisation, to make sure that the PID file exists when the
parent returns.
* bsc#979302: Change the process name of the forking DNS worker
process to avoid the impression that ntpd is started twice.
* bsc#981422: Don't ignore SIGCHILD because it breaks wait().
* Separate the creation of ntp.keys and key #1 in it to avoid problems
when upgrading installations that have the file, but no key #1,
which is needed e.g. by "rcntp addserver".
* bsc#957226: Restrict the parser in the startup script to the first
occurrance of "keys" and "controlkey" in ntp.conf.
* Enable compile-time support for MS-SNTP (--enable-ntp-signd)
* bsc#975496: Fix ntp-sntp-dst.patch.
* bsc#962318: Call /usr/sbin/sntp with full path to synchronize in
start-ntpd. When run as cron job, /usr/sbin/ is not in the path,
which caused the synchronization to fail.
* bsc#782060: Speedup ntpq.
* bsc#951559: Fix the TZ offset output of sntp during DST.
* bsc#916617: Add /var/db/ntp-kod.
* bsc#951351: Add ntp-ENOBUFS.patch to limit a warning that might
happen quite a lot on loaded systems.
* Add ntp-fork.patch and build with threads disabled to allow name
resolution even when running chrooted.
* bnc#784760: Remove local clock from default configuration.
* Fix incomplete backporting of "rcntp ntptimemset".
* bsc#936327: Use ntpq instead of deprecated ntpdc in start-ntpd.
* Don't let "keysdir" lines in ntp.conf trigger the
"keys" parser.
* bsc#910063: Fix the comment regarding addserver in ntp.conf.
* bsc#944300: Remove "kod" from the restrict line in ntp.conf.
* bsc#905885: Use SHA1 instead of MD5 for symmetric keys.
* bsc#926510: Re-add chroot support, but mark it as deprecated and
disable it by default.
* bsc#920895: Drop support for running chrooted, because it is an
ongoing source of problems and not really needed anymore, given that
ntp now drops privileges and runs under apparmor.
* bsc#920183: Allow -4 and -6 address qualifiers in "server"
directives.
* Use upstream ntp-wait, because our version is incompatible with the
new ntpq command line syntax.
* bsc#920905: Adjust Util.pm to the Perl version on SLE11.
* bsc#920238: Enable ntpdc for backwards compatibility.
* bsc#920893: Don't use %exclude.
* bsc#988417: Default to NTPD_FORCE_SYNC_ON_STARTUP="yes"
* bsc#988565: Ignore errors when removing extra files during
uninstallation
* bsc#988558: Don't blindly guess the value to use for IP_TOS
