Description Andrej Nemec 2017-09-06 11:56:34 EDT

The read_section function in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows attackers to cause a denial of service (parse_comp_unit heap-based buffer over-read and application crash) via a crafted ELF file.
