From a8d3b8979c27a8dc87971b66a1d9d9282f660596 Mon Sep 17 00:00:00 2001 From: Chen Qi Date: Tue, 13 May 2014 15:46:26 +0800 Subject: openssh: fix for CVE-2014-2532 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.
