Title

GNU Libgcrypt和GnuPG可预测随机数生成漏洞

Description

GNU Libgcrypt和GnuPG（GNU Privacy Guard）都是GNU计划开发的基于GnuPG代码的通用加密库。 GNU Libgcrypt 1.6.3-2+deb8u2之前的版本和GnuPG 1.4.18-7+deb8u2之前的版本中的‘mixing’函数存在可预测随机数生成漏洞，攻击者可利用该漏洞从RNG获得4640 bit数据后，轻易预测接下来的160 bit数据。

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.
