Description Pedro Sampaio 2018-01-29 14:31:32 EST

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. This problem only affects i686.
