Descriptions
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands.
La función log_config_command en el archivo ntp_parser.y en ntpd en NTP anterior a versión 4.2.7p42, permite a los atacantes remotos causar una denegación de servicio (bloqueo de ntpd) por medio de comandos logconfig creados.
It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands.
The Network Time Protocol is used to synchronize a computer's time with another referenced time source. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service. Security Fix: It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted NTP packet to crash ntpd.
