• The addr2line, c++filt, nm and objdump tools now have a default limit on the maximum amount of recursion that is allowed whilst demangling strings. This limit can be disabled if necessary.
• Objdump's --disassemble option can now take a parameter, specifying the starting symbol for disassembly. Disassembly will continue from this symbol up to the next symbol or the end of the function.
• The BFD linker will now report property change in linker map file when merging GNU properties.
• The BFD linker's -t option now doesn't report members within archives, unless -t is given twice. This makes it more useful when generating a list of files that should be packaged for a …

• The x86 assembler now supports a -mvexwig=[0|1] option to control encoding of VEX.W-ignored (WIG) VEX instructions. It also has a new -mx86-used-note=[yes|no] option to generate (or not) x86 GNU property notes.

It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code.

USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM.

Original advisory details:
