GHSA-v367-p58w-98h5

Summary: PyCrypto makes Use of Insufficiently Random Values

Details: 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.
