Details

Type Candidate
Name CVE-2012-2417
Phase Assigned(20120424)

Description

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.
