Description Andrej Nemec 2017-10-10 12:20:43 UTC
decode_line_info in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, mishandles a length calculation, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file, related to read_1_byte.
