An update that solves 30 vulnerabilities and has 6 fixes is

now available.

 

Description:

 

 

This network time protocol server ntp was updated to 4.2.8p6 to fix the

following issues:

 

Also yast2-ntp-client was updated to match some sntp syntax changes.

(bsc#937837)

 

Major functional changes:

- The "sntp" commandline tool changed its option handling in a major way.

- "controlkey 1" is added during update to ntp.conf to allow sntp to work.

- The local clock is being disabled during update.

- ntpd is no longer running chrooted.

 

 

Other functional changes:

- ntp-signd is installed.

- "enable mode7" can be added to the configuration to allow ntdpc to work

as compatibility mode option.

- "kod" was removed from the default restrictions.

- SHA1 keys are used by default instead of MD5 keys.

 

These security issues were fixed:

- CVE-2015-5219: An endless loop due to incorrect precision to double

conversion (bsc#943216).

- CVE-2015-8158: Fixed 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 allows dangerous characters in

filenames (bsc#962802).

- CVE-2015-7975: nextvar() missing length check (bsc#962988).

- CVE-2015-7974: Skeleton Key: Missing key check allows impersonation

between authenticated peers (bsc#962960).

- CVE-2015-7973: Replay attack on authenticated broadcast mode

(bsc#962995).

- CVE-2015-8140: ntpq vulnerable to replay attacks (bsc#962994).

- CVE-2015-8139: Origin Leak: ntpq and ntpdc, disclose origin (bsc#962997).

- CVE-2015-5300: MITM attacker could have forced ntpd to make a step

larger than the panic threshold (bsc#951629).

- CVE-2015-7871: NAK to the Future: Symmetric association authentication

bypass via crypto-NAK (bsc#951608).

- CVE-2015-7855: decodenetnum() will ASSERT botch instead of returning

FAIL on some bogus values (bsc#951608).

- CVE-2015-7854: Password Length Memory Corruption Vulnerability

(bsc#951608).

- CVE-2015-7853: Invalid length data provided by a custom refclock driver

could cause a buffer overflow (bsc#951608).

- CVE-2015-7852: ntpq atoascii() Memory Corruption Vulnerability

(bsc#951608).

- CVE-2015-7851: saveconfig Directory Traversal Vulnerability (bsc#951608).

- CVE-2015-7850: remote config logfile-keyfile (bsc#951608).

- CVE-2015-7849: trusted key use-after-free (bsc#951608).

- CVE-2015-7848: mode 7 loop counter underrun (bsc#951608).

- CVE-2015-7701: Slow memory leak in CRYPTO_ASSOC (bsc#951608).

- CVE-2015-7703: configuration directives "pidfile" and "driftfile" should

only be allowed locally (bsc#951608).

- CVE-2015-7704, CVE-2015-7705: Clients that receive a KoD should validate

the origin timestamp field (bsc#951608).

- CVE-2015-7691, CVE-2015-7692, CVE-2015-7702: Incomplete autokey data

packet length checks (bsc#951608).

 

These non-security issues were fixed:

- fate#320758 bsc#975981: Enable compile-time support for MS-SNTP

(--enable-ntp-signd). This replaces the w32 patches in 4.2.4 that added

the authreg directive.

- 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#916617: Add /var/db/ntp-kod.

- bsc#956773: Add ntp-ENOBUFS.patch to limit a warning that might happen

quite a lot on loaded systems.

- bsc#951559,bsc#975496: Fix the TZ offset output of sntp during DST.

- Add ntp-fork.patch and build with threads disabled to allow name

resolution even when running chrooted.

- Add a controlkey line to /etc/ntp.conf if one does not already exist to

allow runtime configuuration via ntpq.

- bsc#946386: Temporarily disable memlock to avoid problems due to high

memory usage during name resolution.

- bsc#905885: Use SHA1 instead of MD5 for symmetric keys.

- Improve runtime configuration:

* Read keytype from ntp.conf

* Don't write ntp keys to syslog.

- Fix legacy action scripts to pass on command line arguments.

- bsc#944300: Remove "kod" from the restrict line in ntp.conf.

- bsc#936327: Use ntpq instead of deprecated ntpdc in start-ntpd.

- Don't let "keysdir" lines in ntp.conf trigger the "keys" parser.

- Disable mode 7 (ntpdc) again, now that we don't use it anymore.

- Add "addserver" as a new legacy action.

- bsc#910063: Fix the comment regarding addserver in ntp.conf.

- bsc#926510: Disable chroot by default.

- bsc#920238: Enable ntpdc for backwards compatibility.

- bsc#784760: Remove local clock from default configuration.

- bsc#942441/fate#319496: Require perl-Socket6.

- Improve runtime configuration:

* Read keytype from ntp.conf

* Don't write ntp keys to syslog.

- 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.
