Vulnerability from fkie_nvd - Published: 2026-03-09 15:15 - Updated: 2026-03-13 16:44
Severity ?
6.2 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
GNU Binutils thru 2.45.1 readelf contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF loclists data. A logic flaw in the DWARF parsing code can cause readelf to repeatedly print the same table output without making forward progress, resulting in an unbounded output loop that never terminates unless externally interrupted. A local attacker can trigger this behavior by supplying a malicious input file, causing excessive CPU and I/O usage and preventing readelf from completing its analysis.

Un fallo l\u00f3gico en el c\u00f3digo de an\u00e1lisis DWARF puede hacer que readelf imprima repetidamente la misma salida de tabla sin avanzar, lo que resulta en un bucle de salida ilimitado que nunca termina a menos que sea interrumpido externamente. Un atacante local puede desencadenar este comportamiento al proporcionar un archivo de entrada malicioso, causando un uso excesivo de CPU y E/S y evitando que readelf complete su an\u00e1lisis."
