## Description

Apple Mac EFI before 2015-001, as used in OS X before 10.10.4 and other products, does not properly set refresh rates for DDR3 RAM, which might make it easier for remote attackers to conduct row-hammer attacks, and consequently gain privileges or cause a denial of service (memory corruption), by triggering certain patterns of access to memory locations.

## What to do
