Description Pedro Sampaio 2017-07-11 11:01:19 EDT

opcodes/rl78-decode.opc in GNU Binutils 2.28 has an unbounded GETBYTE macro, which allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file during "objdump -D" execution.
