Description Pedro Sampaio 2017-07-11 08:30:07 EDT

The print_insn_score32 function in opcodes/score7-dis.c:552 in GNU Binutils 2.28 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.
