Title

GNU Binutils Binary File Descriptor library堆缓冲区溢出漏洞

Description

GNU Binutils（又名GNU Binary Utilities或binutils）是GNU计划开发的一组编程语言工具程序，它主要用于处理多种格式的目标文件，并提供有连接器、汇编器和其他用于目标文件和档案的工具。Binary File Descriptor（BFD）library（又名libbfd）是其中的一个以各种格式便携式操作对象文件的库。 GNU Binutils 2.31及之前版本中的BFD library的elfcode.h文件的‘bfd_elf32_swap_phdr_in’函数存在堆缓冲区溢出漏洞，该漏洞源于程序包头的数量未被限定。攻击者可通过提交恶意的文件利用该漏洞造成拒绝服务。

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.
