Oracle HTTP Server Use of a Broken or Risky Cryptographic Algorithm Vulnerability - 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 quotBar Mitzvahquot issue.
