gnark-crypto's exponentiation in the pairing target group GT using GLV can give incorrect results

Impact When the exponent is bigger than r, the group order of the pairing target group GT, the exponentiation à la GLV ExpGLV can sometimes give incorrect results compared to normal exponentiation Exp. The issue impacts all users using ExpGLV for exponentiations in GT. This does not impact Exp an...

Ubuntu 15.10 : openssl vulnerability (USN-2883-1)

Antonio Sanso discovered that OpenSSL reused the same private DH exponent for the life of a server process when configured with a X9.42 style parameter file. This could allow a remote attacker to possibly discover the server's private DH exponent when being used with non-safe primes. Note that...

Vulnerability in OpenSSL - DH small subgroups

Historically OpenSSL usually only ever generated DH parameters based on “safe” primes. More recently in version 1.0.2 support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be “safe”. Where an application ...
