Описание
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.
Отчет
This flaw is related to the design of the RC4 protocol and not its implementation. Therefore there are no plans to correct this issue in Red Hat Enterprise Linux 5, 6 and 7. Future updates may disable the use of RC4 in various components.
