An issue was discovered in NTPsec before 1.1.3. An authenticated attacker can write one byte out of bounds in ntpd via a malformed config request, related to config_remotely in ntp_config.c, yyparse in ntp_parser.tab.c, and yyerror in ntp_parser.y.
The product writes data past the end, or before the beginning, of the intended buffer.
