OpenSSL Cryptographic Issues Vulnerability - CVE-2010-0928

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 quotfault-based attack.quot
