Description Pedro Sampaio 2017-07-11 14:58:56 UTC
opcodes/rx-decode.opc in GNU Binutils 2.28 lacks bounds checks for certain scale arrays, 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.
