PyCrypto is the Python Cryptography Toolkit.
An error in the generate() function in ElGamal.py causes PyCrypto to generate weak ElGamal keys.
A remote attacker might be able to derive private keys.
There is no known workaround at this time.
All PyCrypto users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-python/pycrypto-2.6"
