Description Laura Pardo 2018-09-25 16:04:15 EDT

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory access exists in _bfd_stab_section_find_nearest_line in syms.c. Attackers could leverage this vulnerability to cause a denial of service (application crash) via a crafted ELF file.
