## Description

OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II
Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain
signature calculations, and does not verify the signature before providing
it to a caller, which makes it easier for physically proximate attackers to
determine the private key via a modified supply voltage for the
microprocessor, related to a "fault-based attack."
