Title

GNU Binutils libbfd dwarf2.c read_formatted_entries拒绝服务漏洞

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 2.29版本中的BFD库的dwarf2.c文件的read_formatted_entries存在安全漏洞，该漏洞源于程序没有正确的验证格式计数。远程攻击者可借助特制的ELF文件利用该漏洞造成拒绝服务（空指针逆向引用和应用程序崩溃）。

CVE-2017-15023 (GCVE-0-2017-15023)

Vulnerability from cvelistv5 – Published: 2017-10-04 07:00 – Updated: 2024-08-05 19:42

Summary

read_formatted_entries in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, does not properly validate the format count, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ELF file, related to concat_filename.

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.
