Squid拒绝服务漏洞（CNVD-2016-01441）

Description

Squid（全称Squid Cache）是一套代理服务器和Web缓存服务器软件。该软件提供缓存万维网、过滤流量、代理上网等功能。 Squid 3.5.15之前3.x版本和4.0.7之前4.x版本的Edge Side Includes(ESI)解析器中存在安全漏洞，该漏洞源于程序在解析XML期间未能检查缓冲区限制。远程攻击者可借助特制的XML文档利用该漏洞造成拒绝服务（断言失败和守护进程退出）。

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.
