Denial-of-Service in GNU Binutils readelf via Malformed DWARF Data

Publication date: 2026-03-09

Last updated on: 2026-03-13

Assigner: MITRE

Description
GNU Binutils thru 2.45.1 readelf contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF .debug_rnglists data. A logic flaw in the DWARF parsing path causes readelf to repeatedly print the same warning message without making forward progress, resulting in a non-terminating output loop that requires manual interruption. No evidence of memory corruption or code execution was observed.

Executive Summary

This vulnerability exists in GNU Binutils through version 2.45.1, specifically in the readelf tool. It is a denial-of-service issue triggered when readelf processes a specially crafted binary containing malformed DWARF .debug_rnglists data. Due to a logic flaw in the DWARF parsing code, readelf enters a non-terminating loop where it repeatedly prints the same warning message without progressing, requiring manual interruption to stop.

Impact Analysis

The primary impact of this vulnerability is a denial-of-service condition when using the readelf tool on maliciously crafted binaries. This causes readelf to hang in an infinite loop of warning messages, which can disrupt workflows or automated processes relying on readelf. However, there is no evidence that this vulnerability leads to memory corruption or code execution.
