Description Pedro Sampaio 2017-07-11 14:45:32 UTC 
The *regs* macros in opcodes/bfin-dis.c in GNU Binutils 2.28 allow 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.
