    CVE ID         : CVE-2006-4339

    Daniel Bleichenbacher discovered a flaw in OpenSSL cryptographic package
    that could allow an attacker to generate a forged signature that OpenSSL
    will accept as valid.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 0.9.6m-1sarge2
    
    This package exists only for compatibility with older software, and is
    not present in the unstable or testing branches of Debian.
    
    We recommend that you upgrade your openssl packages.  Note that services
    linking against the openssl shared libraries will need to be restarted.
    Common examples of such services include most Mail Transport Agents, SSH
    servers, and web servers.
    
    Upgrade Instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
