CVE-2015-2808

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.
