Descriptions

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.

La función Crypto.Random.atfork en PyCrypto anterior a 2.6.1 no reestablece correctamente la semilla en el generador de números pseudoaleatorios (PRNG) antes de permitir el acceso a un proceso hijo, lo cual facilita a atacantes dependientes del contexto obtener información sensible provocando una condición de carrera en la cual un proceso hijo es creado y accede el PRNG con el mismo límite de periodo que otro proceso.
