Title

strongSwan ASN.1解析器拒绝服务漏洞

Description

strongSwan是瑞士软件开发者Andreas Steffen所维护的一套Linux平台使用的开源的基于IPsec的VPN解决方案。该方案包含X.509公开密钥证书、安全储存私钥、智能卡等认证机制。ASN.1 parser是一个用来解析ASN.1的工具。 strongSwan 5.5.3之前的版本中的ASN.1解析器存在拒绝服务漏洞，该漏洞源于在x509插件启动时程序未能正确处理CHOICE类型。远程攻击者可利用该漏洞造成拒绝服务。

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.
