Description Laura Pardo 2018-09-25 20:09:43 UTC

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_zalloc in opncls.c. Attackers could leverage this vulnerability to cause a denial of service (application crash) via a crafted ELF file.
