Title

MIT Kerberos 5缓冲区溢出漏洞

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。 MIT Kerberos 5 1.14 beta2版本的lib/gssapi/krb5/iakerb.c文件中的‘iakerb_gss_export_sec_context’函数存在安全漏洞。由于程序未能正确使用指针。远程攻击者可通过与调用‘gss_export_sec_context’函数的应用程序交互利用该漏洞造成拒绝服务（内存损坏）。（说明：该漏洞由于CNNVD-201511-133补丁的不完全修复存在）

CVE-2015-2698 (GCVE-0-2015-2698)

Vulnerability from cvelistv5 – Published: 2015-11-13 02:00 – Updated: 2024-08-06 05:24

Summary

The iakerb_gss_export_sec_context function in lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) 1.14 pre-release 2015-09-14 improperly accesses a certain pointer, which allows remote authenticated users to cause a denial of service (memory corruption) or possibly have unspecified other impact by interacting with an application that calls the gss_export_sec_context function. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-2696.

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.
