    Multiple vulnerabilities have been discovered in OpenSSL:
    
    CVE-2014-0195
    
        Jueri Aedla discovered that a buffer overflow in processing DTLS
        fragments could lead to the execution of arbitrary code or denial
        of service.
    
    CVE-2014-0221
    
        Imre Rad discovered the processing of DTLS hello packets is 
        susceptible to denial of service.
    
    CVE-2014-0224
    
        KIKUCHI Masashi discovered that carefully crafted handshakes can
        force the use of weak keys, resulting in potential man-in-the-middle
        attacks.
    
    CVE-2014-3470
    
        Felix Groebert and Ivan Fratric discovered that the implementation of
        anonymous ECDH ciphersuites is suspectible to denial of service.

    For the stable distribution (wheezy), these problems have been fixed in
    version 1.0.1e-2+deb7u10. All applications linked to openssl need to
    be restarted. You can use the tool checkrestart from the package
    debian-goodies to detect affected programs or reboot your system. There's
    also a forthcoming security update for the Linux kernel later the day
    (CVE-2014-3153), so you need to reboot anyway. Perfect timing, isn't it?
    
    For the unstable distribution (sid), these problems will be fixed soon.
    
    We recommend that you upgrade your openssl packages.
