Descriptions
Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.
Desbordamiento de búfer en la función decodearr en ntpq en ntp, desde la versión 4.2.8p6 hasta la 4.2.8p10, permite que atacantes remotos ejecuten código arbitrario aprovechando una consulta ntpq y enviando una respuesta con un array manipulado.
Yihan Lian discovered that NTP incorrectly handled certain malformed mode 6 packets. A remote attacker could possibly use this issue to cause ntpd to crash, resulting in a denial of service. This issue only affected Ubuntu 17.10 and Ubuntu 18.04 LTS. Michael Macnair discovered that NTP incorrectly handled certain responses. A remote attacker could possibly use this issue to execute arbitrary code. Various other issues were also addressed.
