CVE-2013-1445

NameCVE-2013-1445
DescriptionThe 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.
SourceCVE (at NVD; oss-sec, fulldisc, OSVDB, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, more)
