CVE-2013-2566

Description

From CVE.org

The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.

Statement

This flaw is related to the design of the RC4 protocol and not its implementation. More details and a possible work around is mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=921947#c8. Therefore there are no plans to correct this issue in Red Hat Enterprise Linux 5 and 6.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
