Title

NTP ntpd输入验证漏洞

Description

ntpd（Network Time Protocol daemon）是一个操作系统守护进程，它使用网络时间协议（NTP）与时间服务器的系统时间保持同步。 NTP 4.2.8及之前版本的ntpd中的ntp_crypto.c文件存在安全漏洞。远程攻击者可通过发送包含可执行字段（该字段中包含无效的长度值）的数据包利用该漏洞获取进程内存中的敏感信息，或造成拒绝服务（守护进程崩溃）。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
