Title

MIT Kerberos 5 Key Distribution Center拒绝服务漏洞

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。Key Distribution Center（KDC）是其中的一个秘钥分发中心组件。 MIT krb5中的KDC的plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c文件存在安全漏洞。远程攻击者可借助已更改的kadmin客户端利用该漏洞造成拒绝服务（空指针逆向引用）。

CVE-2018-5710 (GCVE-0-2018-5710)

Vulnerability from cvelistv5 – Published: 2018-01-16 09:00 – Updated: 2024-08-05 05:40

Summary

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client.
