SSL/TLS: Attack against RC4 stream cipher
Published Mar 14, 2013
5.9
MEDIUMCVSS 3.1
EPSS 84.42%
Description
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.

Remediation
Red Hat statement
This flaw is related to the design of the RC4 protocol and not its implementation. More details and a possible work around is mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=921947#c8. Therefore there are no plans to correct this issue in Red Hat Enterprise Linux 5 and 6.
