CVE-2013-1445 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:17.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-crypto package and not the python-crypto package as distributed by Ubuntu.
The Crypto.Random.atfork function in PyCrypto before 2.6.1 does not properly reseed the pseudo-random number generator (PRNG) before allowing a child process to access it, which makes it easier for context-dependent attackers to obtain sensitive information by leveraging a race condition in which a child process is created and accesses the PRNG within the same rate-limit period as another process.
