Attackers can craft malicious ELF binaries with traversal sequences to probe filesystem existence and leak CRC32 hashes of arbitrary files during automatic DWARF analysis."

Los atacantes pueden crear binarios ELF maliciosos con secuencias de salto para sondear la existencia del sistema de archivos y filtrar hashes CRC32 de archivos arbitrarios durante el análisis DWARF automático."
