The bfd_make_section_with_flags function in section.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause a NULL dereference via a crafted file.
The nlm_swap_auxiliary_headers_in function in bfd/nlmcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause an out of bounds heap read via a crafted nlm file.
The bfd_mach_o_read_symtab_strtab function in bfd/mach-o.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause an out of bounds heap write and possibly achieve code execution via a crafted mach-o file.
