scan_unit_for_symbols in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ELF file.
scan_unit_for_symbols en dwarf2.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.29 y anteriores permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) mediante un archivo ELF manipulado.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM. It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
