bfd_malloc_and_get_section does size sanity checking before allocating memory and reading contents. These size checks are not done for bss style sections, because they typically don't occupy file space and thus can't be compared against file size. However, if you are expecting to look at something other than a whole lot of zeros, don't allow fuzzers to avoid the size checking. * cofflink.c (process_embedded_commands): Don't look at sections without SEC_HAS_CONTENTS set. * cpu-arm.c (bfd_arm_update_notes): Likewise.
