Descriptions

The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

La función elf_object_p en elfcode.h en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.29.1, tiene un desbordamiento de enteros no firmados debido a que no se emplea la multiplicación bfd_size_type. Un archivo ELF manipulado permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) o, posiblemente, otro impacto sin especificar.

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.
