The issue is related to the ignore section sym function in the elf.c file of the Binary File Descriptor (BFD) library, which is part of GNU Binutils. This function does not validate the output section pointer in the case of a symtab entry with a "SECTION" type that has a "0" value. As a result, remote attackers can cause a denial of service, leading to a NULL pointer dereference and application crash, by providing a crafted file. For example, this can be demonstrated using objcopy.
