Mandriva Linux Security Advisory : openssh (MDVSA-2014:068)

This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated openssh packages fixes security vulnerabilities :

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 (CVE-2014-2532).

Matthew Vernon reported that if a SSH server offers a HostCertificate
that the ssh client doesn't accept, then the client doesn't check the
DNS for SSHFP records. As a consequence a malicious server can disable
SSHFP-checking by presenting a certificate (CVE-2014-2653).
