How to fix?

Upgrade Ubuntu:16.04 binutils to version 2.26.1-1ubuntu1~16.04.8+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h because the number of program headers is not restricted.
