"The RC4 algorithm, as used in the TLS protocol and SSL protocol, does
not properly combine state data with key data during the
initialization phase, which makes it easier for remote attackers to
conduct plaintext-recovery attacks against the initial bytes of a
stream by sniffing network traffic that occasionally relies on keys
affected by the Invariance Weakness, and then using a brute-force
approach involving LSB values, aka the 'Bar Mitzvah' issue.
