Efficient and Effective Buffer Overflow Protection on ARM Processors
Abstract : Although many countermeasures have been developed
for desktop and server environments, buffer overflows still pose a big
threat. The same approach can be used to target mobile devices.
Unfortunately, they place more severe limitations on countermeasures.
Not only are the performance requirements at least as important, memory
and power consumption need to be considered as well. Moreover,
processors used in mobile devices generally are equipped with a
different instruction set. Therefore countermeasures may not be ported
easily. Multistack is an effective countermeasure against stack-based
buffer overflows. It protects applications by using multiple stacks to
separate possible attack targets from possible sources. However, its
performance overhead will no longer be negligible on the ARMv7 platform
(widely used on mobile devices) and it wastes too much memory, making it
too costly for mobile applications. We propose 3 methods to reduce
memory overhead up to 28% with only a 3.91% performance
overhead.
