Descriptions

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer underflow or overflow, and application crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm.

dwarf2.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, permite que atacantes remotos provoquen una denegación de servicio (desbordamiento o subdesbordamiento de enteros y cierre inesperado de la aplicación) mediante un archivo ELF con un bloque DWARF FORM corrupto, tal y como demuestra nm.

An integer wraparound has been discovered in the Binary File Descriptor (BFD) library distributed in GNU Binutils up to version 2.30. An attacker could cause a crash by providing an ELF file with corrupted DWARF debug information.
