    Package        : strongswan
    CVE ID         : CVE-2015-4171
    
    Alexander E. Patrakov discovered an issue in strongSwan, an IKE/IPsec
    suite used to establish IPsec protected links.
    
    When an IKEv2 client authenticates the server with certificates and the
    client authenticates itself to the server using pre-shared key or EAP,
    the constraints on the server certificate are only enforced by the
    client after all authentication steps are completed successfully. A
    rogue server which can authenticate using a valid certificate issued by
    any CA trusted by the client could trick the user into continuing the
    authentication, revealing the username and password digest (for EAP) or
    even the cleartext password (if EAP-GTC is accepted).
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 4.5.2-1.5+deb7u7.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 5.2.1-6+deb8u1.
    
    For the testing distribution (stretch), this problem has been fixed
    in version 5.3.1-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 5.3.1-1.
    
    We recommend that you upgrade your strongswan packages.
