CVE-2011-0766
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
