Descriptions

The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys.

El generador de números aleatorios de la aplicación Crypto en versiones anteriores a la 2.0.2.2, y SSH anteriores a 2.0.5, como es usado en la librería Erlang/OTP ssh en versiones anteriores a la R14B03, utiliza semillas predecibles basadas en la fecha actual, lo que facilita a atacantes remotos adivinar el host DSA y las claves de sesión SSH.
