Vulnerability from fkie_nvd - Published: 2026-03-06 18:16 - Updated: 2026-03-10 17:24
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug_rnglists data. A logic error in the handling of the debug_rnglists header can cause objdump to repeatedly print the same warning message and fail to terminate, resulting in an unbounded logging loop until the process is interrupted. The issue was observed in binutils 2.44. A local attacker can exploit this vulnerability by supplying a malicious input file, leading to excessive CPU and I/O usage and preventing completion of the objdump analysis.

Un error l\u00f3gico en el manejo del encabezado debug_rnglists puede hacer que objdump imprima repetidamente el mismo mensaje de advertencia y no termine, lo que resulta en un bucle de registro ilimitado hasta que el proceso sea interrumpido. El problema se observ\u00f3 en binutils 2.44. Un atacante local puede explotar esta vulnerabilidad al proporcionar un archivo de entrada malicioso, lo que lleva a un uso excesivo de CPU y E/S y evitando la finalizaci\u00f3n del an\u00e1lisis de objdump."
