Title

OpenSSL 1.1.0a版本任意代码执行漏洞

Description

OpenSSL是一种开放源码的SSL实现，用来实现网络通信的高强度加密，现在被广泛地用于各种网络应用程序中。 OpenSSL 1.1.0a版本存在任意代码执行漏洞，当系统收到超过大约16K大小的消息时，准备接受该消息的缓冲区会在其他地方重新分配，这时会产生一个指向原缓冲区的悬空指针，允许将新数据写入这片已经释放过的区域。攻击者利用漏洞可执行任意代码。

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.
