CVE-2015-2808

Severity CVSS v4.0:
Pending analysis
Type:
CWE-327 Use of a Broken or Risky Cryptographic Algorithm
Publication date:
01/04/2015
Last modified:

Description

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.
