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.");
