CVE-2013-1445
mediumpriority · track · 18EPSS 0.017 · 78 %ileEUUSEPSS · scored 2026-10-27
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.
