Integer Overflow

OpenSSL is vulnerable to integer overflows. It exists due to a mishandling of overflow in rsaz512sqr for the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli...

CVE-2019-1551 rsaz_512_sqr overflow bug on x86_64

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...
