Vulnerability from cnvd - Published: 2017-09-20

Title

Tcpdump ISO CLNS解析器缓冲区

Description

Tcpdump是Tcpdump团队开发的一套运行在命令行下的嗅探工具。该工具允许用户拦截和显示发送或收到过网络连接到该计算机的TCP/IP和其他数据包。ISO CLNS parser是其中的一个CLNS（无连接网络服务）解析器。 Tcpdump 4.9.2之前的版本中的ISO CLNS解析器的print-isoclns.c文件的‘isoclns_print()’函数存在缓冲区溢出漏洞。远程攻击者可利用该漏洞造成拒绝服务（缓冲区越边界读取和应用程序崩溃）。

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.
