In previous versions of PyCrypto, the Crypto.Random PRNG exhibits a race condition that may cause forked processes to generate identical sequences of ‘random’ numbers.
This release fixes the problem by resetting the rate-limiter when Crypto.Random.atfork() is invoked.
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.
