Received Received - Intake
Denial-of-Service in Binutils objdump via Malformed DWARF Data

Publication date: 2026-03-06

Last updated on: 2026-03-10

Assigner: MITRE

Description
An issue was discovered in Binutils before 2.46. The objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed debug information. A logic flaw in the handling of DWARF location list headers can cause objdump to enter an unbounded loop and produce endless output until manually interrupted. This issue affects versions prior to the upstream fix and allows a local attacker to cause excessive resource consumption by supplying a malicious input file.

Executive Summary

This vulnerability exists in Binutils versions before 2.46, specifically in the objdump tool. It is caused by a logic flaw in how objdump processes DWARF location list headers within debug information of binary files. When objdump encounters a crafted binary with malformed debug information, it can enter an unbounded loop, producing endless output until manually stopped.

Impact Analysis

The vulnerability allows a local attacker to cause a denial-of-service by supplying a malicious input file to objdump. This results in excessive resource consumption as objdump enters an infinite loop and produces endless output, potentially disrupting normal operations or analysis workflows.
