Title

MIT Kerberos 5 kadmind拒绝服务漏洞（CNVD-2016-01135）

Description

MIT Kerberos 5（又名krb5）是美国麻省理工学院（MIT）开发的一套网络认证协议，它采用客户端/服务器结构，并且客户端和服务器端均可对对方进行身份认证（即双重验证），可防止窃听、防止replay攻击等。 MIT Kerberos 5的kadmind服务程序中的lib/kadm5/srv/svr_principal.c文件中的‘kadm5_create_principal_3’函数和‘kadm5_modify_principal’函数存在安全漏洞。远程攻击者可通过指定带有空策略名的KADM5_POLICY利用该漏洞造成拒绝服务（空指针逆向引用和守护进程崩溃）。

Detection rules are retrieved from Rulezet.

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.
