Description

The assign_file_positions_for_non_load_sections function in elf.c 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 (NULL pointer dereference and application crash) via an ELF file with a RELRO segment that lacks a matching LOAD segment, as demonstrated by objcopy.
