| pycrypto | = 1.0.0= 1.0.1= 1.0.2= 1.1= 1.9= 2.0= 2.0.1= 2.1.0= 2.2= 2.3= 2.4= 2.4.1≤ 2.5 |
PyCrypto before 2.6 does not produce appropriate prime numbers when using an ElGamal scheme to generate a key, which reduces the signature space or public key space and makes it easier for attackers to conduct brute force attacks to obtain the private key.
