The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many
single-byte biases, which makes it easier for remote attackers to conduct
plaintext-recovery attacks via statistical analysis of ciphertext in a
large number of sessions that use the same plaintext.
jdstrand> this is a protocol problem not specific to openssl. Using openssl
as a placeholder until more information is available
jdstrand> marking low for now until more information is available. At present,
naive attacks need tens to hundreds of millions of TLS connections. Optimized
attacks are not present yet.

just disable RC4)
mdeslaur> marking as ignored since there is no actionable item
