CVE-2018-7642 is a vulnerability of currently unknown severity. The swap_std_reloc_in function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (aout_32_swap_std_reloc_out NULL pointer dereference and application crash) via a crafted ELF file, as demonstrated by objcopy.. EPSS estimates a 1.95% chance of exploitation in the next 30 days.
