Title

Ruby OpenSSL::ASN1模块缓冲区下溢漏洞

Description

Ruby是日本软件开发者松本行弘所研发的一种跨平台、面向对象的动态类型编程语言。OpenSSL::ASN1 module是其中的一个ASN1数据解码模块。 Ruby 2.2.8之前的版本、2.3.5之前的2.3.x版本和2.4.x版本至2.4.1版本中的OpenSSL::ASN1模块的解密方法存在安全漏洞。攻击者可借助特制的字符串利用该漏洞造成拒绝服务（解释器崩溃）。

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.
