Description Andrej Nemec 2017-10-10 13:13:45 UTC 
bfd_get_debug_link_info_1 in opncls.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file, related to bfd_getl32.
