Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

US-CERT reports :

The Erlang/OTP ssh library implements a number of cryptographic
operations that depend on cryptographically strong random numbers.
Unfortunately the RNG used by the library is not cryptographically
strong, and is further weakened by the use of predictable seed
material. The RNG (Wichman-Hill) is not mixed with an entropy source.
