Description

This update is a security fix for CVE-2012-2417 (insecure ElGamal key generation). Anyone using ElGamal keys should generate new keys as soon as practical (any additional information about this bug will be tracked at https://bugs.launchpad.net/pycrypto/+bug/985164).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
