CVE-2013-1445
python-crypto - PRNG not correctly reseeded in some situations
7.5
HIGH
CVSS 3.1
EPSS 2.0%
描述
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.
