decode_line_info in dwarf2.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 (divide-by-zero error and
application crash) via a crafted ELF file.

SUSE will not provide a fix for this issue since the risk to our customers posed by it is negligible.
