    Package        : strongswan
    Vulnerability  : authentication bypass
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2012-2388
    
    An authentication bypass issue was discovered by the Codenomicon CROSS
    project in strongSwan, an IPsec-based VPN solution. When using
    RSA-based setups, a missing check in the gmp plugin could allow an
    attacker presenting a forged signature to successfully authenticate
    against a strongSwan responder.
    
    The default configuration in Debian does not use the gmp plugin for
    RSA operations but rather the OpenSSL plugin, so the packages as
    shipped by Debian are not vulnerable.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4.4.1-5.2.
    
    For the testing distribution (wheezy), this problem has been fixed in
    version 4.5.2-1.4.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.5.2-1.4.
    
    We recommend that you upgrade your strongswan packages.
