CVE-2019-1551

CVE-2019-1551 refers to an overflow bug in the x64_64 Montgomery squaring procedure used in OpenSSL during exponentiation with 512-bit moduli. OpenSSL notes no impact to EC, while DH512 attacks are only just feasible under certain conditions. Public disclosures and advisories confirm the issue an...

CVE-2019-1551

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...

CVE-2016-7055

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...
