27 Jan 2016 — The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename. El comando savconfig ntpq en NTP 4.1.2, 4.2.x en versiones anteriores a 4.2.8p6, 4.3, 4.3.25, 4.3.70 y 4.3.77 no filtra adecuadamente caracteres especiales, lo que permite a atacantes causar un impacto no especificado a través de un nombre de archivo manipulado.

CVSS: 7.7EPSS: 4%CPEs: 29EXPL: 1CVE-2015-7974 – ntp: missing key check allows impersonation between authenticated peers (VU#357792)
https://notcve.org/view.php?id=CVE-2015-7974
26 Jan 2016 — NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." NTP 4.x en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 no verifica las asociaciones del par de las claves simétricas cuando autentica paquetes, lo que podría permitir a atacante remotos llevar a cabo ataques de suplantación de identidad a... • http://bugs.ntp.org/show_bug.cgi?id=2936 • CWE-287: Improper Authentication CWE-304: Missing Critical Step in Authentication •
CVSS: 6.4EPSS: 6%CPEs: 90EXPL: 0CVE-2015-8138 – ntp: missing check for zero originate timestamp
https://notcve.org/view.php?id=CVE-2015-8138
25 Jan 2016 — NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to bypass the origin timestamp validation via a packet with an origin timestamp set to zero. NTP en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 permite a atacantes remotos eludir la validación de marca horaria de origen a través de un paquete con una marca horaria de origen puesta a cero. It was discovered that ntpd as a client did not correctly check the originate timestamp in received packets. A remote attacker ... • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html • CWE-20: Improper Input Validation CWE-294: Authentication Bypass by Capture-replay •
