openssl: Integer overflow in RSAZ modular exponentiation on x86_64

An integer overflow was found in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. As per upstream: No EC algorithms are affected. Attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...
