CVE-2013-1445: Dlitz Pycrypto

Medium severity, CVSS 4.3. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products
