Description Pedro Sampaio 2017-07-10 20:37:53 UTC 
The print_insn_score16 function in opcodes/score7-dis.c 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.
