Vulnerability from fkie_nvd - Published: 2011-05-31 20:55 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
