VuXML ID	e4833927-86e5-11e0-a6b4-000a5e1e33c6
Discovery	2011-05-25
Entry	2011-05-25

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.
