These security issues were fixed: - 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). 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. - bsc#784760: Remove local clock from default configuration The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0). slessp4-ntp-12533 Copyright SUSE LLC under the Creative Commons License 4.0 with Attribution (CC-BY-4.0) https://www.suse.com/support/update/announcement/2016/suse-su-20161175-1/ Link for SUSE-SU-2016:1175-1 https://lists.suse.com/pipermail/sle-security-updates/2016-April/002032.html E-Mail link for SUSE-SU-2016:1175-1 https://www.suse.com/support/security/rating/ SUSE Security Ratings https://bugzilla.suse.com/782060 SUSE Bug 782060 https://bugzilla.suse.com/784760 SUSE Bug 784760 https://bugzilla.suse.com/916617 SUSE Bug 916617 https://bugzilla.suse.com/951559 SUSE Bug 951559 https://bugzilla.suse.com/951629 SUSE Bug 951629 https://bugzilla.suse.com/956773 SUSE Bug 956773 https://bugzilla.suse.com/962318 SUSE Bug 962318 https://bugzilla.suse.com/962784 SUSE Bug 962784 https://bugzilla.suse.com/962802 SUSE Bug 962802 https://bugzilla.suse.com/962960 SUSE Bug 962960 https://bugzilla.suse.com/962966 SUSE Bug 962966 https://bugzilla.suse.com/962970 SUSE Bug 962970 https://bugzilla.suse.com/962988 SUSE Bug 962988 https://bugzilla.suse.com/962994 SUSE Bug 962994 https://bugzilla.suse.com/962995 SUSE Bug 962995 https://bugzilla.suse.com/962997 SUSE Bug 962997 https://bugzilla.suse.com/963000 SUSE Bug 963000 https://bugzilla.suse.com/963002 SUSE Bug 963002 https://bugzilla.suse.com/975496 SUSE Bug 975496 https://bugzilla.suse.com/975981 SUSE Bug 975981 https://www.suse.com/security/cve/CVE-2015-5300/ SUSE CVE CVE-2015-5300 page https://www.suse.com/security/cve/CVE-2015-7973/ SUSE CVE CVE-2015-7973 page https://www.suse.com/security/cve/CVE-2015-7974/ SUSE CVE CVE-2015-7974 page https://www.suse.com/security/cve/CVE-2015-7975/ SUSE CVE CVE-2015-7975 page https://www.suse.com/security/cve/CVE-2015-7976/ SUSE CVE CVE-2015-7976 page https://www.suse.com/security/cve/CVE-2015-7977/ SUSE CVE CVE-2015-7977 page https://www.suse.com/security/cve/CVE-2015-7978/ SUSE CVE CVE-2015-7978 page https://www.suse.com/security/cve/CVE-2015-7979/ SUSE CVE CVE-2015-7979 page https://www.suse.com/security/cve/CVE-2015-8138/ SUSE CVE CVE-2015-8138 page https://www.suse.com/security/cve/CVE-2015-8139/ SUSE CVE CVE-2015-8139 page https://www.suse.com/security/cve/CVE-2015-8140/ SUSE CVE CVE-2015-8140 page https://www.suse.com/security/cve/CVE-2015-8158/ SUSE CVE CVE-2015-8158 page SUSE Linux Enterprise Server 11 SP4 SUSE Linux Enterprise Server for SAP Applications 11 SP4 ntp-4.2.8p6-8.2 ntp-doc-4.2.8p6-8.2 ntp-4.2.8p6-8.2 as a component of SUSE Linux Enterprise Server 11 SP4 ntp-doc-4.2.8p6-8.2 as a component of SUSE Linux Enterprise Server 11 SP4 ntp-4.2.8p6-8.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 ntp-doc-4.2.8p6-8.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart).
