    Two vulnerabilities were discovered in OpenSSH, an implementation of the
    SSH protocol suite. The Common Vulnerabilities and Exposures project
    identifies the following problems:
    
    CVE-2014-2532
    
        Jann Horn discovered that OpenSSH incorrectly handled wildcards in
        AcceptEnv lines. A remote attacker could use this issue to trick
        OpenSSH into accepting any environment variable that contains the
        characters before the wildcard character.
    
    CVE-2014-2653
    
        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.
    
        Note that a host verification prompt is still displayed before
        connecting.
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 1:5.5p1-6+squeeze5.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1:6.0p1-4+deb7u1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:6.6p1-1.
    
    We recommend that you upgrade your openssh packages.
