    Kevin Wojtysiak discovered a vulnerability in strongSwan, an IPsec based VPN
    solution.
    
    When using the openssl plugin for ECDSA based authentication, an empty, zeroed
    or otherwise invalid signature is handled as a legitimate one. An attacker
    could use a forged signature to authenticate like a legitimate user and gain
    access to the VPN (and everything protected by this).
    
    While the issue looks like CVE-2012-2388 (RSA signature based authentication
    bypass), it is unrelated.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4.4.1-5.3.
    
    For the testing distribution (wheezy), this problem has been fixed in
    version 4.5.2-1.5+deb7u1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.6.4-7.
    
    We recommend that you upgrade your strongswan packages.
