Description Pedro Sampaio 2017-07-11 11:12:09 EDT

opcodes/i386-dis.c in GNU Binutils 2.28 does not consider the number of registers for bnd mode, 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.
