"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.

"Upgrade the openssl packages.

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?"
