PYSEC-2013-29

Vulnerability from pysec - Published: 2013-10-26 17:55 - Updated: 2021-08-27 03:22

Details

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.
