CVE-2017-15939

Priority
Description
dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as
distributed in GNU Binutils 2.29, mishandles NULL files in a .debug_line
file table, which allows remote attackers to cause a denial of service
(NULL pointer dereference and application crash) via a crafted ELF file,
related to concat_filename. NOTE: this issue is caused by an incomplete fix
for CVE-2017-15023.
