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.

CVE-2011-0766 [HIGH] CVE-2011-0766 erlang: SSH library uses a weak random number generator
CVE-2011-0766 erlang: SSH library uses a weak random number generator
Geoff Cant reported that the Erlang/OTP SSH library's random number generator
relied on predictable seed information. A remote attacker could use this flaw
to recover SSH session keys or DSA host keys.
