CVE-2014-2532 [Medium] | Input Validation Bypass in Communications User Data …

sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character.
