medium Nessus Plugin ID 70517

Language:

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.

Solution

Update the affected packages.
