Descriptions
The nextvar function in NTP before 4.2.8p6 and 4.3.x before 4.3.90 does not properly validate the length of its input, which allows an attacker to cause a denial of service (application crash).
La función nextvar en NTP en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 no valida correctamente la longitud de su entrada, lo que permite a un atacante provocar una denegación de servicio (caída de la aplicación).
Aanchal Malhotra discovered that NTP incorrectly handled authenticated broadcast mode. A remote attacker could use this issue to perform a replay attack. Matt Street discovered that NTP incorrectly verified peer associations of symmetric keys. A remote attacker could use this issue to perform an impersonation attack. Jonathan Gardner discovered that the NTP ntpq utility incorrectly handled memory. An attacker could possibly use this issue to cause ntpq to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS. Various other issues were also addressed.
