Description Pedro Sampaio 2017-07-11 11:14:21 EDT

The aarch64_ext_ldst_reglist function in opcodes/aarch64-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.
