How to fix?

Upgrade RHEL:7 java-1.7.0-openjdk-demo to version 1:1.7.0.85-2.6.1.2.el7_1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream java-1.7.0-openjdk-demo package and not the java-1.7.0-openjdk-demo package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
