Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Dwayne Litzenberger reports :

In PyCrypto before v2.6.1, the Crypto.Random pseudo-random number
generator (PRNG) exhibits a race condition that may cause it to
generate the same 'random' output in multiple processes that are
forked from each other. Depending on the application, this could
reveal sensitive information or cryptographic keys to remote
attackers.
