| Package | Affected versions | Patched versions |
|---|---|---|
| pycrypto | < 2.6.1 | 2.6.1 |
| pycrypto | = 1.0.0= 1.0.1= 1.0.2= 2.0= 2.0.1= 2.1.0= 2.2= 2.3= 2.4= 2.4.1= 2.5≤ 2.6 |
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.
