Insecure PRNG Reseeding in PyCrypto's Crypto.Random.atfork Function

CVE-2013-1445 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:N/A:N

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.
