Title

GNU Binutils越界读取漏洞

Description

GNU Binutils是一组用于创建和管理二进制程序、对象文件、库、配置文件数据及程序集源代码的编程工具。 GNU Binutils 2.32中使用的二进制文件描述符（BFD）库（即libbfd）存在越界读取漏洞。攻击者可利用该漏洞导致libbfd.c中的bfd_getl32发生SEGV（当从pei-x86_64.c中的pex64_get_runtime_function调用时）导致泄露敏感信息，添加或修改数据或拒绝服务（DoS）。

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.
