Vulnerability from fkie_nvd - Published: 2017-09-30 01:29 - Updated: 2026-06-17 01:07
Severity
Summary
decode_line_info in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, mishandles a length calculation, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file, related to read_1_byte.

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.
