Description Andrej Nemec 2017-05-10 09:07:03 UTC
The function coff_set_alignment_hook in coffcode.h in Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils has a memory leak vulnerability which can cause memory exhaustion in objdump via a crafted PE file. Additional validation in dump_relocs_in_section in objdump.c can resolve this.
